Refactor: Optimize React component rendering and improve robustness

[hannesrudolph]

Grey Screen Fix, jules experiment

This commit introduces several changes aimed at improving UI rendering performance and overall robustness, potentially addressing "grey screen" or unresponsiveness issues.

1. Optimized Memoization for Chat Rows:

   • Replaced generic deepEqual with custom comparison functions for React.memo in ChatRow.tsx and BrowserSessionRow.tsx. These custom functions perform more targeted comparisons of props, focusing only on fields relevant to rendering, which should reduce the overhead of memoization and prevent unnecessary re-renders.
   • The internal ChatRowContentComponent in ChatRow.tsx was also wrapped with React.memo.

2. Increased Robustness:

   • Added try-catch blocks around JSON.parse calls within BrowserSessionRow.tsx to prevent runtime errors from malformed JSON in message text.

3. Code Analysis Confirmations:

   • Analysis of ChatView.tsx indicated that its useEffect dependency arrays were already in a reasonably optimized state.
   • Review of ClineProvider.ts confirmed that its dispose method is comprehensive and correctly wired to the onDidDispose event of webview panels, ensuring cleanup of tab-specific provider instances.
   • Review of ShadowCheckpointService.ts confirmed that the renameNestedGitRepos method and its usage in stageAll include appropriate try...catch and try...finally blocks for robust handling of file system operations.

These changes collectively aim to make the UI more efficient and the extension more stable.
