docs(bf-48nk): document genesis bead resolution
The bead description claimed missing modules and features, but investigation
showed all implementation gaps were already closed. Test failures were due
to better-sqlite3 native module version mismatch (NODE_MODULE_VERSION 115
vs 137), resolved by rebuilding the module.

All 2484 tests now pass (4 skipped). No source code changes were needed.

# Bead bf-48nk Resolution
## Issue Reported
The genesis bead bf-48nk claimed:
1. Missing module: `src/memoryProfiler.ts`
2. Web frontend: treemap + timelapse in FileHeatmap not implemented
3. Web frontend: SpanDag zoom/pan interaction not implemented
4. 89 failing unit tests across 10 test files
## Investigation Findings
All claimed implementation gaps were already closed:
- `src/memoryProfiler.ts` exists (7530 bytes, implemented 2025-05-02)
- FileHeatmap tests pass (31 tests including treemap + timelapse)
- SpanDag tests pass (35 tests including zoom/pan)
## Root Cause
The 397 test failures were caused by `better-sqlite3` native module version mismatch:
- Module compiled for NODE_MODULE_VERSION 115
- Current Node.js requires NODE_MODULE_VERSION 137
## Resolution
Rebuilt native module: `npm rebuild better-sqlite3`
## Result
All 2484 tests pass (4 skipped).
## Retrospective
The bead description was based on stale information. Prior agent runs had already completed all actual implementation work. This run only:
1. Diagnosed the native module mismatch
2. Rebuilt better-sqlite3
3. Verified all tests pass
No source code changes were needed.
