Add Warp as Fleet maintained app for macOS (#41051)

## Summary

- Adds Warp terminal as a Fleet maintained app for macOS (darwin)
- Uses direct CDN URL (`releases.warp.dev`) instead of Homebrew's URL
which requires `User-Agent: Homebrew` header
- Single `WarpDirectInstaller` enricher: overrides URL, sets `sha256:
no_check`, strips `.stable_` from version string
- Version: `0.2026.02.25.08.24.01` (latest stable)

## Validation checklist

- [ ] App can be downloaded using manifest URL
- [ ] App installs successfully on macOS host using manifest install
script
- [ ] App exists in software inventory after install
(`dev.warp.Warp-Stable`)
- [ ] App uninstalls successfully using manifest uninstall script

## Notes

Supersedes #37901 (branch had corrupted git history from a rewrite; this
is a clean branch off main).
