fix(e2e): remove duplicate cli/.env.e2e.example; fix TS2345 in global-setup

- Delete cli/.env.e2e.example (root-level duplicate).
  The canonical template is cli/test/e2e/.env.e2e.example.

- Add missing @ts-expect-error before the early-return project.provide()
  call in global-setup.ts (line 167). The second call at line 290 already
  had the suppressor; the first one was accidentally left without it,
  causing TS2345 in the CLI Tests CI.

+/**
+ * e2e-provision.ts
+ *
+ * Standalone pre-flight script for CI parallel e2e jobs.
+ *
+ * What it does (mirrors global-setup.ts, but without vitest):
+ *   1. Console login → cookie + CSRF token
+ *   2. Mint a primary bearer token (or validate a cached/pre-set one)
+ *   3. Discover primary + secondary workspaces
+ *   4. Provision all DSL fixture apps (idempotent — reuses existing ones)
+ *   5. Write GITHUB_OUTPUT (token, workspace IDs, all app IDs)
+ *      so downstream jobs can skip re-minting and re-provisioning.
+ *
+ * Usage (in CI):
+ *   bun scripts/e2e-provision.ts
+ *
+ * Required env vars:
+ *   DIFY_E2E_HOST, DIFY_E2E_EMAIL, DIFY_E2E_PASSWORD
+ *
+ * Optional:
+ *   DIFY_E2E_EDITION      (ee | ce, default: ee)
+ *   DIFY_E2E_TOKEN        pre-minted token — skips device-flow mint
+ *
+ * Output file:
+ *   .provision-output.json   (also written to GITHUB_OUTPUT if set)

+# Dify CLI — E2E Test Suite
+
+End-to-end tests that exercise the **real `difyctl` binary** against a live
+Dify server. Every test uses an isolated temporary config directory so no
+state leaks between test files.

+## Edition support
+
+`difyctl` supports two Dify editions. The test suite adapts automatically:
+
+| Edition                 | `DIFY_E2E_EDITION` | Workspaces       | EE-only cases |
+| ----------------------- | ------------------ | ---------------- | ------------- |
+| Community Edition (CE)  | `ce` (default)     | 1                | Skipped       |
+| Enterprise Edition (EE) | `ee`               | 2 (auto-created) | Active        |
+
+### EE-only test cases
+
+Tests that require Enterprise Edition features (workspace switching between
+independent workspaces, cross-workspace app query, etc.) are tagged `[EE]`
+in their names and wrapped with `enterpriseOnlyIt()` / `enterpriseOnlyDescribe()`
+from `helpers/skip.ts`. In CE mode these tests are automatically skipped.
+
+```ts
+// helpers/skip.ts usage
+const eeIt = enterpriseOnlyIt(caps)
+eeIt('[EE][P0] cross-workspace query returns apps from all workspaces', async () => {
+  // test body
+})
+```
+
+## Setup
+
+Copy the credential template and fill in your values:
+
+```bash
+cp cli/test/e2e/.env.e2e.example cli/.env.e2e
+# edit cli/.env.e2e with real credentials
+```
+
+### Community Edition (CE) — minimum 3 vars
+
+| Variable            | Description                                           |
+| ------------------- | ----------------------------------------------------- |
+| `DIFY_E2E_HOST`     | Server base URL (`http://localhost`)                  |
+| `DIFY_E2E_EMAIL`    | Account email — created automatically by global-setup |
+| `DIFY_E2E_PASSWORD` | Account password                                      |
+
+global-setup will:
+
+1. Register the account (idempotent — safe to rerun)
+1. Login and mint a bearer token via the device flow
+1. Import all DSL fixtures into the single workspace
+1. Publish apps and set access_mode → public
+
+### Enterprise Edition (EE) — 5 required vars
+
+| Variable                             | Description                                             |
+| ------------------------------------ | ------------------------------------------------------- |
+| `DIFY_E2E_EDITION`                   | Must be `ee`                                            |
+| `DIFY_E2E_HOST`                      | Console/API base URL                                    |
+| `DIFY_E2E_EMAIL`                     | Member account email — created via enterprise API       |
+| `DIFY_E2E_PASSWORD`                  | Member account password                                 |
+| `DIFY_E2E_ENTERPRISE_API_URL`        | Enterprise admin API base URL (`https://.../inner/api`) |
+| `DIFY_E2E_ENTERPRISE_API_SECRET_KEY` | Enterprise admin API secret key                         |
+
+Optional:
+
+| Variable               | Description                                   |
+| ---------------------- | --------------------------------------------- |
+| `DIFY_E2E_CONSOLE_URL` | Console URL if different from `DIFY_E2E_HOST` |
+
+global-setup will:
+
+1. Create the member account via the enterprise admin API (idempotent)
+1. Login and obtain a session cookie
+1. Create two workspaces (`e2e-primary-auto`, `e2e-secondary-auto`) via the enterprise API
+1. Import DSL fixtures into both workspaces
+1. Publish apps and set access_mode → public via the enterprise API
+
+### Optional overrides (both editions)
+
+| Variable                             | Description                                      |
+| ------------------------------------ | ------------------------------------------------ |
+| `DIFY_E2E_TOKEN`                     | Pre-minted bearer token — skips device-flow mint |
+| `DIFY_E2E_SSO_TOKEN`                 | External SSO bearer token (`dfoe_...`)           |
+| `DIFY_E2E_WORKSPACE_ID`              | Override primary workspace ID                    |
+| `DIFY_E2E_WORKSPACE_NAME`            | Override primary workspace name                  |
+| `DIFY_E2E_WS2_ID`                    | Override secondary workspace ID (EE)             |
+| `DIFY_E2E_CHAT_APP_ID`               | Override echo-chat app ID                        |
+| `DIFY_E2E_WORKFLOW_APP_ID`           | Override echo-workflow app ID                    |
+| `DIFY_E2E_FILE_APP_ID`               | Override file-upload app ID                      |

+| `DIFY_E2E_HITL_EXTERNAL_APP_ID`      |                                                  |
+| `DIFY_E2E_HITL_SINGLE_ACTION_APP_ID` |                                                  |
+| `DIFY_E2E_HITL_MULTI_NODE_APP_ID`    |                                                  |
+| `DIFY_E2E_WS2_APP_ID`                | Override secondary workspace app ID (EE)         |
+
+## Running tests
+
+```bash
+cd cli
+
+# Community Edition (default)
+bun run test:e2e
+
+# Enterprise Edition
+DIFY_E2E_EDITION=ee bun run test:e2e
+
+# Run only [P0] smoke cases
+bun run test:e2e:smoke
+
+# Run only EE-tagged cases (P0 smoke)
+DIFY_E2E_EDITION=ee bun run test:e2e:smoke --testNamePattern "\[EE\]"
+
+# Run offline-safe config tests only (no network required)
+bun run test:e2e:local
+
+# Run a single file
+bun vitest --config vitest.e2e.config.ts test/e2e/suites/auth/status.e2e.ts
+```
+
+## Test execution order
+
+Files run sequentially (`fileParallelism: false`) in this order:
+
+```
+login → status → use → whoami → help → config → output → error-handling
+  → framework → discovery → run (basic / streaming / file / HITL)
+  → devices → logout
+```
+
+`devices` and `logout` run last because they revoke real server sessions.
+
+## Design decisions
+
+| Decision                                | Rationale                                                                                                                  |
+| --------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- |
+| **CE/EE edition flag**                  | `DIFY_E2E_EDITION=ce/ee` controls global-setup bootstrap path and activates/skips `[EE]`-tagged tests.                     |
+| **`[EE]` tag convention**               | Test names include `[EE]` to make skipped cases visible in the report and to allow `--testNamePattern "\[EE\]"` filtering. |
+| **`enterpriseOnlyIt(caps)`**            | Returns `it` in EE mode, `it.skip` in CE mode — no runtime assertions needed, skip is declarative.                         |
+| **No mocking**                          | All HTTP traffic goes to the real server — this catches real integration regressions.                                      |
+| **Isolated config dirs**                | Each test creates a fresh `withTempConfig()` dir; session state never leaks between tests.                                 |
+| **`withAuthFixture()`**                 | Combines `withTempConfig` + `injectAuth` into a single fixture; reduces beforeEach boilerplate.                            |
+| **`injectAuth()` bypasses Device Flow** | Non-auth tests skip the browser step; only `auth/` suites exercise the real flow.                                          |
+| **`mintFreshToken()`**                  | `logout` and `devices-revoke` tests mint a disposable `dfoa_` token via the device flow API.                               |
+| **Global `retry: 0`**                   | Flaky network calls use `withRetry()` locally; global retry masks non-idempotent failures.                                 |
+| **Conversation cleanup**                | `registerConversation()` + global-teardown delete staging conversations after the run.                                     |

+ *   the **CLI-observable** parts of the login command:

+ *     - Network-unreachable error path (1.13)
+ *     - Credential file permissions after write (1.8)
+ *     - Initial Device Flow output (stderr contains code + URL) before OAuth completes (1.2)
+ *     - Cross-host warning when a session already exists (1.10)
+ *     - --no-browser prompt format (1.16)
+ *     - Invalid URL input rejection via stdin (1.17)
+ *
+ *   Cases that require completing real OAuth (1.1, 1.3–1.7, 1.9, 1.11, 1.12, 1.15) are

+ *  1. Top-level help overview  (difyctl help / difyctl --help / difyctl -h / difyctl <no args>)
+ *  2. Per-command help via --help flag  (e.g. auth login --help)
+ *  3. help <topic> subcommands  (help account / help external / help environment)
+ *  4. Unknown command help routing
+ *
+ * Key behaviours confirmed by local testing:
+ *  - `difyctl help`, `difyctl --help`, `difyctl -h`, `difyctl` all output the same top-level help
+ *  - `difyctl help account/external/environment` routes via the help flag path:
+ *    helpArgv = ['account'] / ['external'] / ['environment'] → resolveCommand fails
+ *    → falls back to printTopLevelHelp() (same as top-level help)
+ *  - `difyctl help account --help` also prints top-level help (--help strips before resolve)
+ *  - Per-command help: `difyctl auth login --help` → formatHelp() output with USAGE/FLAGS/EXAMPLES
+ *  - No auth is required for any help invocation
+ *  - Exit code is always 0 for help commands

+ *   5.43  -o yaml | yq . — yq is not guaranteed to be present in CI.

+ *   5.49  failed command + -o yaml stable — CLI outputs a JSON error
+ *         envelope on stderr regardless of -o flag; covered by 5.40/5.41.
