Fix three Cursor chat regressions observed on first message runs: 1. Full-screen UI refresh/flicker after first response. 2. Internal wrapper tags rendered in user messages. 3. Duplicate assistant message on response finalization. Root causes - Project refresh from chat completion used the global loading path, toggling app-level loading UI. - Cursor history conversion rendered raw internal wrapper payloads as user-visible message text. - Cursor response handling could finalize through overlapping stream/ result paths, and stdout chunk parsing could split JSON lines. Changes - Added non-blocking project refresh plumbing for chat/session flows. - Introduced fetch options in useProjectsState (showLoadingState flag). - Added refreshProjectsSilently() to update metadata without global loading UI. - Wired window.refreshProjects to refreshProjectsSilently in AppContent. - Added Cursor user-message sanitization during history conversion. - Added extractCursorUserQuery() to keep only <user_query> payload. - Added sanitizeCursorUserMessageText() to strip internal wrappers: <user_info>, <agent_skills>, <available_skills>, <environment_context>, <environment_info>. - Applied sanitization only for role === 'user' in convertCursorSessionMessages(). - Hardened Cursor backend stream parsing and finalization. - Added line-buffered stdout parser for chunk-split JSON payloads. - Flushed trailing unterminated stdout line on process close. - Removed redundant content_block_stop emission on Cursor result. - Added frontend duplicate guard in cursor-result handling. - Skips a second assistant bubble when final result text equals already-rendered streamed content. Code comments - Added focused comments describing silent refresh behavior, tag stripping rationale, duplicate guard behavior, and line buffering. Validation - ESLint passes for touched files. - Production build succeeds.
