PrimeCode v1.5.3

Server health monitor: Added periodic /global/health polling in ChatProvider (15s interval, 3-failure threshold) for proactive server health diagnostics without intrusive reconnection.
SSE bridge reliability: Refactored backend status event stream with exponential backoff retry (250ms–30s range) and per-iteration AbortController to fix listener leakage on stream reconnects.
Retry logic for Webview health checks: Header health checker now performs up to 2 retries with 100ms delay for transient network errors, plus 750ms promise caching to deduplicate rapid rechecks.
Error resilience: Added ConfigInvalidError detection in bootstrap — invalid project config now shows a user-facing notification instead of a generic error. Improved error logging across opencodeRuntime, proxyFetch, and eventRuntime.
Global ErrorBoundary: Implemented a top-level React ErrorBoundary in the Webview to catch render crashes gracefully.

Fixed provider model visibility so ModelDropdown and ProviderManager correctly reflect available models.
Fixed streaming card rendering for subagent UI states.
Removed automatic notification dismissal — users now dismiss notifications manually for better visibility.
Fixed notification title truncation: replaced truncate with line-clamp-5 for multi-line notification titles.
Removed unnecessary session reconcile on every server.connected heartbeat — session data arrives via individual SSE events.
Fixed proxyFetch abort signal cleanup: no longer leaks 'abort' listeners; properly distinguishes network failures (reject) from HTTP 4xx/5xx responses (returned as Response).

Enhanced ScrollThumb component with alwaysVisible and thumbColor props for better scrollbar customization.
Updated MessageItem with pending status icon during message submission.
Improved markdown table styling for better readability.
Added OpencodeEventMessage type and unified event handling across ChatProvider and eventRuntime.
Enhanced copy actions throughout header and chat components for easier content extraction.

Added comprehensive test suites for BackendStatusBridge, eventRuntime, proxyFetch, and openCodeRuntime, covering lifecycle, event filtering, coalescing, error handling, and abort behavior.
