feat: Implement Gate 3 timeline pipeline and Gate 4 migration scaffolding
Complete 5 beads for the Phase B temporal intelligence feature:
- bd-1oo: Register migration 015 (commit SHAs, closes watermark) and
create migration 016 (mr_file_changes table with 4 indexes for
Gate 4 file-history)
- bd-20e: Define TimelineEvent model with 9 event type variants,
EntityRef, ExpandedEntityRef, UnresolvedRef, and TimelineResult
types. Ord impl for chronological sorting with stable tiebreak.
- bd-32q: Implement timeline seed phase - FTS5 keyword search to
entity IDs with discussion-to-parent resolution, entity dedup,
and evidence note extraction with snippet truncation.
- bd-ypa: Implement timeline expand phase - BFS cross-reference
expansion over entity_references with bidirectional traversal,
depth limiting, mention filtering, provenance tracking, and
unresolved reference collection.
- bd-3as: Implement timeline event collection - gathers Created,
StateChanged, LabelAdded/Removed, MilestoneSet/Removed, Merged,
and NoteEvidence events. Merged dedup (state=merged -> Merged
variant only). NULL label/milestone fallbacks. Chronological
interleaving with since filter and limit.
38 new tests, all 445 tests pass. All quality gates clean.
