fix(cli): honor no-color for policy output

[mjq2020]

Summary

• honor the standard NO_COLOR environment variable for every policy-list status
• add a global --no-color flag that works before or after the subcommand
• route existing hard-coded ANSI policy output through the shared TUI painter
• cover the environment-variable and CLI-flag paths with unit and E2E regressions

Root cause

listHooks() embedded ANSI escape sequences directly, bypassing the shared color painter, and the CLI did not recognize a color-suppression flag. Consequently NO_COLOR=1 failproofai policies still emitted escapes and failproofai policies --no-color failed argument validation.

Tests

• rebased onto upstream main at 653f116
• focused manager tests: 58/58 passed
• focused CLI argument E2E tests: 60/60 passed
• full E2E suite with required system git: 317 passed, 6 skipped, 0 failed
• bun x tsc --noEmit
• bun run lint
• bun run build
• packed tarball clean-installed globally in node:22-bookworm; both NO_COLOR=1 failproofai policies and failproofai policies --no-color exited successfully with no ESC bytes

The full unit suite's touched manager file passed 58/58. The repository baseline and this branch both show the same unrelated HOME-sensitive failures under a bind-mounted Docker workspace; representative baseline/branch runs matched exactly (18 failures in dashboard-cache, daemon-download, and integrations tests).

Fixes #688

Summary by CodeRabbit

• New Features

  • Added a global --no-color option, accepted anywhere in the command.
  • Policy listings and hook output now honor both --no-color and NO_COLOR.
  • Updated command help to document the new option.

• Bug Fixes

  • Preserved checkmarks, warnings, informational messages, and errors while removing ANSI color codes when color is disabled.

• Documentation

  • Added release notes for version 1.0.2-beta.0.

📝 Walkthrough

Walkthrough

The CLI accepts global --no-color handling. Policy and hook output uses paint and honors NO_COLOR. Tests verify plain output, preserved status text, and the absence of ANSI escape sequences.

Changes

Policy color control

Layer / File(s)	Summary
CLI no-color option bin/failproofai.mjs	The CLI accepts --no-color in any argument position, sets NO_COLOR=1, removes the flag before validation, and documents it in help output.
Policy output formatting src/hooks/manager.ts	Policy and hook statuses, warnings, headings, and errors use paint methods that honor NO_COLOR.
Color suppression validation and release note __tests__/hooks/manager.test.ts, __tests__/e2e/cli/cli-args.e2e.test.ts, CHANGELOG.md	Tests verify plain policy output and retained status text. The changelog records the fix.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 53a56

This localized CLI behavior fix is merge-ready after normal checks and review; no actionable merge-blocking risk remains.

Poem

A rabbit checks the flags at dawn,
Then prints plain text when color’s gone.
Checkmarks stay, warnings remain,
ANSI escapes leave the train.
Policies hop cleanly through the log.

🚥 Pre-merge checks | ✅ 5

✅ Passed checks (5 passed)

Check name	Status	Explanation
Linked Issues check	✅ Passed	The changes satisfy issue #688 by supporting NO_COLOR and --no-color, routing output through paint(), documenting the flag, and adding tests.
Out of Scope Changes check	✅ Passed	The changelog updates and added unit and E2E tests directly support the issue objectives; no unrelated code changes are identified.
Docstring Coverage	✅ Passed	Docstring check was indeterminate for this PR — some files could not be analyzed in time. Not blocking.
Description check	✅ Passed	The description clearly explains the change, root cause, tests, and issue reference, but it omits the template's Type of Change and Checklist sections.
Title check	✅ Passed	The title clearly and concisely identifies the main change: honoring no-color behavior for policy output.

escapes” test coverage to invoke the CLI with --no-color before the policies
subcommand, while preserving the existing success, output, and no-ANSI
assertions to verify preprocessing supports both argument orders.
