feat(import): implement parent resurrection (bd-cc4f, bd-d76d, bd-02a4)

Phase 2 of fixing import failure on missing parent issues (bd-d19a).

Implemented:
- TryResurrectParent: searches JSONL history for deleted parents
- TryResurrectParentChain: recursively resurrects entire parent chains
- Creates tombstones (status=closed) to preserve hierarchical structure
- Modified EnsureIDs and CreateIssue to call resurrection before validation

When importing a child issue with missing parent:
1. Searches .beads/issues.jsonl for parent in git history
2. If found, creates tombstone with status=closed
3. Preserves original title and metadata
4. Appends original description to tombstone
5. Copies dependencies if targets exist

This allows imports to proceed even when parents were deleted,
enabling multi-repo workflows and normal database hygiene operations.

Part of bd-d19a (fix import failure on missing parents).
