- Implemented bd merge command with dual-mode operation: 1. Git 3-way merge: bd merge <output> <base> <left> <right> 2. Duplicate issue merge: bd merge <sources...> --into <target> (placeholder) - Added MergeFiles wrapper to internal/merge package - Command works without database when used as git merge driver - Supports --debug flag for verbose output - Exit code 0 for clean merge, 1 for conflicts - Handles deletions intelligently (delete-modify conflicts) - Added proper MIT license attribution for @neongreen's beads-merge code - Tests pass for git merge functionality This enables git merge driver setup for .beads/beads.jsonl files.
