feat(glab): add ci and release subcommand filtering

Add token-optimized filtering for two more glab subcommand groups:

CI/CD pipelines:
- `glab ci list`: Compact pipeline listing with status icons (~90% savings)
- `glab ci trace`: Strip ANSI codes, section markers, runner boilerplate,
  git fetch noise, and artifact upload details. Keep commands, build output,
  warnings, errors, and job result.

Releases:
- `glab release list`: Passthrough (already compact text output)
- `glab release view`: Strip SOURCES block (archive URLs are noise),
  filter markdown noise (HTML comments, images, horizontal rules)

Also:
- Add lazy_static regex for CI section markers and bare ANSI codes
- Update discover rules pattern and savings estimates
- Add test fixtures and unit tests for all new filters
