- Chat.tsx: rewritten to use global chatStore singleton — SSE connection survives
page navigation; added StopCircle cancel button; scrolls only when near bottom
- chatStore.ts: new module-level singleton (EventTarget pattern) that holds all
conversation/console state; TextDecoder with stream:true for correct UTF-8
- handlers.go (ProvidersReload): now accepts decrypted key in request body from
Node.js so Go gateway can actually use the API key without sharing crypto logic
- providers.ts (activateProvider): sends decrypted key to gateway via
notifyGatewayReload(); seedDefaultProvider also calls notifyGatewayReload()
- seed.ts: on startup, after seeding, pushes active provider to gateway with
retry loop (5 retries × 3 s) to wait for gateway readiness
- index.ts (SSE proxy): TextDecoder('utf-8', {stream:true}) already correct;
confirmed Cyrillic text arrives ungarbled (e.g. 'Привет!' not '??????????')
