* feat(server): add memory health statistics API endpoints
Add two new API endpoints for querying aggregate memory health:
- GET /stats/memories - global memory stats (counts by category,
hotness distribution, staleness metrics)
- GET /stats/sessions/{id} - per-session extraction statistics
The StatsAggregator reads from existing VikingDB indexes and the
hotness_score function without introducing new storage.
Includes unit tests with mocked VikingDB backend.
* feat(parse): implement audio resource parser with Whisper transcription
Replace the audio parser stub with a working implementation that:
- Extracts metadata (duration, sample rate, channels, bitrate) via mutagen
- Transcribes speech via Whisper API with timestamped segments
- Builds structured ResourceNode tree with L0/L1/L2 content tiers
- Falls back to metadata-only output when Whisper is unavailable
- Adds mutagen as optional dependency under [audio] extra
- Adds audio_summary prompt template for semantic indexing
- Includes unit tests with mocked Whisper API and mutagen
* style: format with ruff
* Revert audio parser changes from this branch
The audio parser feature is unrelated to memory health stats and
belongs in its own PR (#707). Reverts audio.py to pre-rewrite state,
removes the unused audio_summary.yaml template and audio parser tests.

* Address review feedback: fix N+1 query, remove total_vectors, fix error handling
- Replace per-category _query_memories_by_category with single
_query_all_memories call, grouping by category in Python (1 DB
round-trip instead of 8)
- Remove misleading total_vectors field (was identical to
total_memories). Will add real vector count from VikingDB index
stats in a follow-up
- Distinguish KeyError (session not found) from other failures in
stats.py endpoint, returning INTERNAL_ERROR for unexpected exceptions

* fix(stats): align tests with review feedback changes
- Remove total_vectors assertions (field was removed per review)
- Use KeyError instead of Exception for session-not-found test
- Add test_session_internal_error to verify INTERNAL_ERROR for
unexpected exceptions (was previously swallowed as NOT_FOUND)
* fix(deps): remove leftover audio optional dependency
The `audio` optional dependency group (`mutagen>=1.47.0`) was left
over from the reverted audio parser commit (898cc8e). It belongs in
#707 with the audio parser feature, not in this stats API PR.
