test(cli): add integration test suite for Discovery, Run, Output, Error Handling and CLI Framework

Add comprehensive integration tests under cli/test/testcases/ covering:

Discovery:
- App list (list, single, all-workspaces)
- Describe App
- Cross-workspace query

Run:
- Basic App execution
- Streaming output
- HITL (Human-in-the-Loop) — all 19 cases incl. multi-action / expired-token / already-consumed
- File input
- Conversation mode
- Environment variable injection
- Cache and version consistency

Output:
- JSON/YAML output
- Table output

Error Handling:
- Exit code end-to-end validation
- Error message spec

CLI Framework:
- Global Flags
- Non-Interactive mode

Also extend test fixtures:
- scenarios.ts: add hitl-pause-multi-action / hitl-resume-expired-token / hitl-resume-already-consumed
- server.ts: add GET /form/human_input route, multi-action HITL response, expired/consumed token error handling

Known bugs tracked as it.todo:
- WTA-249: server 4xx in -o json mode exit code should be 1 (currently 0 in some cases)
- WTA-252: --help missing GLOBAL FLAGS section and Quick start examples
- WTA-255: hosts.yml YAML parse failure should output JSON envelope
- WTA-257: uncaught TypeError should output JSON envelope in -o json mode
