Gas town agents need to ignore working-file directories like .logs,
.runtime, and .claude, but Beads provides its own .gitignore handling
in `bd init`, creating a .beads/.gitignore file which ignores the
relevant Beads working files while allowing .beads/issues.jsonl
to be tracked correctly. PR #753 broke this, causing new polecats
to attempt to merge their changed .gitignore into the project repo,
ultimately breaking bd sync and causing issues to become untracked.
Add EnsureGitignorePatterns to rig package that ensures .gitignore
has required Gas Town patterns (.runtime/, .claude/, .beads/, .logs/).
Called from crew and polecat managers when creating new workers.
This prevents runtime-gitignore warnings from gt doctor.
The function:
- Creates .gitignore if it doesn't exist
- Appends missing patterns to existing files
- Recognizes pattern variants (.runtime vs .runtime/)
- Adds "# Gas Town" header when appending
Includes comprehensive tests for all scenarios.
Two improvements:
1. gt crew start now infers rig from cwd when first arg is not a valid
rig name (gt-czltv). Previously, running `gt crew start bob` from
within a rig directory would fail because "bob" was treated as the
rig name. Now it checks if the arg is a valid rig first.
2. Refactored copyOverlay to shared rig.CopyOverlay utility:
- Eliminates code duplication between crew and polecat managers
- Preserves source file permissions instead of hardcoding 0644
- Follows PR #278 improvements
