All `except Exception:` now catch as `except Exception as exc:` with
appropriate logging (warning for critical paths, debug for graceful degradation).
Added logger setup to 4 files that lacked it:
- src/timmy/memory/vector_store.py
- src/dashboard/middleware/csrf.py
- src/dashboard/middleware/security_headers.py
- src/spark/memory.py
31 files changed across timmy core, dashboard, infrastructure, integrations.
Zero bare excepts remain. 1340 tests passing.
Three fixes from real-world testing:
1. Event loop: replaced asyncio.run() with a persistent loop so
Agno's MCP sessions survive across conversation turns. No more
'Event loop is closed' errors on turn 2+.
2. Markdown stripping: voice preamble tells Timmy to respond in
natural spoken language, plus _strip_markdown() as a safety net
removes **bold**, *italic*, bullets, headers, code fences, etc.
TTS no longer reads 'asterisk asterisk'.
3. MCP noise: _suppress_mcp_noise() quiets mcp/agno/httpx loggers
during voice mode so the terminal shows clean transcript only.
32 tests (12 new for markdown stripping + persistent loop).
