Auto-invoke 3-way merge for JSONL conflicts (bd-jjua)

When git pull encounters merge conflicts in .beads/beads.jsonl, the
post-merge hook runs 'bd sync --import-only' which previously failed
with an error message pointing users to manual resolution.

This commit adds automatic 3-way merge resolution as a fallback safety
net that works alongside the git merge driver.

Changes:
- Modified conflict detection in import.go to attempt automatic merge
- Added attemptAutoMerge() function that:
  - Extracts git conflict stages (:1 base, :2 ours, :3 theirs)
  - Invokes 'bd merge' command for intelligent field-level merging
  - Writes merged result back and auto-stages the file
  - Restarts import with merged JSONL on success
- Falls back to manual resolution instructions only if auto-merge fails

Defense-in-depth approach:
1. Primary: git merge driver prevents most conflicts during merge
2. Fallback: import auto-merge handles any that slip through
