ChatCrystal v0.4.21

Desktop & Cloud

• Improved Electron cloud connection diagnostics so network-level failures explain invalid 0.0.0.0 client addresses and Windows Docker Desktop host/LAN port caveats instead of surfacing raw TypeError: fetch failed.
• Moved Electron cloud local-history upload into a worker process so scanning and uploading local AI histories no longer blocks the Electron main process.
• Added an Electron cloud-mode sidebar action for uploading local histories directly from the desktop app without showing CLI instructions.
• Unified the Electron default and minimum window size at 1280x800 so reconnect/onboarding layouts do not reopen in a too-narrow saved window.
• Changed the Docker Compose cloud binding default to 0.0.0.0 while documenting when to use loopback behind a local reverse proxy.
• Documented Windows Docker Desktop host-port caveats for LAN IP testing of Docker cloud deployments.

Search & Demo

• Reduced misleading semantic-search confidence by filtering weak vector hits that miss required query terms and promoting strong lexical matches above weak vector neighbors.
• Relabeled search result percentages as relevance and refreshed demo screenshots with the current UI.
• Made demo seeding clear the demo vector index so screenshot/demo data does not reuse stale semantic-search results.
