fix(hindsight): overhaul hindsight memory plugin and memory setup wizard

- Dedicated asyncio event loop for Hindsight async calls (fixes aiohttp session leaks)
- Client caching (reuse instead of creating per-call)
- Local mode daemon management with config change detection and auto-restart
- Memory mode support (hybrid/context/tools) and prefetch method (recall/reflect)
- Proper shutdown with event loop and client cleanup
- Disable HindsightEmbedded.__del__ to avoid GC loop errors
- Update API URLs (app -> ui.hindsight.vectorize.io, api_url -> base_url)
- Setup wizard: conditional fields (when clause), dynamic defaults (default_from)
- Switch dependency install from pip to uv (correct for uv-based venvs)
- Add hindsight-all to plugin.yaml and import mapping
- 12 new tests for dispatch routing and setup field filtering
