#!/usr/bin/env bash
# scripts/release-build.sh — cross-compile difyctl to standalone binaries
# for every release target via `bun build --compile`.
#
# Bun consumes bin/run.ts (which imports from src/) directly — no `pnpm build`
# / dist/ step needed.
#
# Prereqs:
#   - All @napi-rs/keyring native variants present in node_modules. Use
#     `NPM_CONFIG_USERCONFIG=cli/scripts/cross-arch.npmrc pnpm install --force`
#     to populate them.
#
# Env (all optional; defaults derived from cli/package.json + git):
#   CLI_VERSION        — package.json `version`
#   DIFYCTL_CHANNEL    — package.json `difyctl.channel`
#   DIFYCTL_MIN_DIFY   — package.json `difyctl.compat.minDify`
#   DIFYCTL_MAX_DIFY   — package.json `difyctl.compat.maxDify`
#   DIFYCTL_COMMIT     — `git rev-parse HEAD` (or "unknown")
#   DIFYCTL_BUILD_DATE — current UTC time
#
# Output: dist/bin/difyctl-v<CLI_VERSION>-<target>[.exe]
