feat: Add bd merge command for git 3-way JSONL merging (bd-omx1)
- 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.

This command is idempotent and safe to retry after partial failures:
|

1. Validates all issues exist and no self-merge
|
||||
2. Migrates all dependencies from sources to target (skips if already exist)
|
||||
3. Updates text references in all issue descriptions/notes
|
||||
4. Closes source issues with reason 'Merged into bd-X' (skips if already closed)
|
||||
Example:
|

bd merge bd-42 bd-43 --into bd-41
|
||||
bd merge bd-10 bd-11 bd-12 --into bd-10 --dry-run`,

Use: "merge <source-ids...> --into <target-id> | merge <output> <base> <left> <right>",
|

Short: "Merge duplicate issues or perform 3-way JSONL merge",
|

Long: `Two modes of operation:
|
||||
|
||||
1. Duplicate issue merge (--into flag):
|
||||
bd merge <source-id...> --into <target-id>
|
||||
Consolidates duplicate issues into a single target issue.

|

2. Git 3-way merge (4 positional args, no --into):
|

bd merge <output> <base> <left> <right>
|

Performs intelligent field-level JSONL merging for git merge driver.

- Dependencies merged with union + dedup
|

- Timestamps use max(left, right)

- Status/priority use 3-way comparison

- Detects deleted-vs-modified conflicts
