* feat(dev): add safe git operations for AI agents
Adds agent-safe commands to prevent common git mistakes:
- `core dev sync <file> --to="pattern"`: Sync files across repos
- Auto-pulls before copying (safe sync)
- Optional commit with --message
- Optional push with --push
- Dry-run mode with --dry-run
- `core dev apply --command="..."`: Run commands across repos
- Execute shell commands in each repo
- Execute scripts with --script
- Optional commit/push after changes
- Continue on error with --continue
- Filter repos with --repos
Safety features:
- Never force push
- Auto-pull before push on rejection
- Report failures without stopping other repos
- Dry-run support for previewing changes
Closes#53

* fix(dev): address CodeRabbit review feedback
- Use errors.E() for consistent error handling in cmd_apply.go and cmd_file_sync.go
- Add path traversal validation to reject ".." in source paths
- Execute scripts directly to honor shebangs (not via sh)
