When sync.branch is configured, issues.jsonl appears modified in git status
even though changes go to the sync branch. This is confusing for users and
risks accidental commits to the wrong branch.
Implementation:
- Added SyncBranchGitignore() to set git index flags (assume-unchanged,
skip-worktree) on issues.jsonl when sync.branch is configured
- For untracked files, adds to .git/info/exclude instead
- Called automatically from bd sync after successful sync-branch sync
- Added bd doctor check and fix for this issue
- Added HasSyncBranchGitignoreFlags() to check current flag state
- Added ClearSyncBranchGitignore() to remove flags when sync.branch disabled
Fixes: GH#870 (duplicate of GH#797, GH#801)
