Add --id flag to bd list for filtering by specific issue IDs

- Add --id flag accepting comma-separated IDs
- Implements ID filtering at CLI, RPC, and storage layers
- Normalizes IDs (trim, dedupe, remove empty) like labels
- Guards against excessive ID lists (max 1000)
- Works with other filters (status, priority, etc.)

Closes bd-200
