* fix(files): refresh open file content after external edits Previously, opening a file in the Files view and then editing it externally (e.g. via CLI or another editor) would show stale content. Even closing and reopening the file returned cached content — a full page reload was required. Root causes: 1. The in-memory readFile cache used path-only hits, with no metadata validation. External edits were invisible until the cache was evicted. 2. No polling mechanism existed to detect external changes to the open file. Fix: - Add mtimeMs to statFile across all runtimes (web, VS Code, desktop). - Cache layer (RuntimeAPIProvider): validate cache hits against current stat metadata (mtimeMs + size). On miss, use stat→read→stat to avoid TOCTOU. - UI layer (FilesView): poll the open file every 2s; on detected change, set loadedFilePath=null to trigger the existing load effect once (no double reload). Skip polling when tab is hidden or editor has unsaved changes. - After save, refresh the stat ref so the next poll doesn't see a spurious change from the save itself. Addresses review feedback from PR #827 (double reload + TOCTOU). * fix(files): address P2 review findings - readFreshFile retry now uses stat→read→stat to maintain TOCTOU protection during the retry path (not just the initial read). - Replace isDirty in polling effect deps with isDirtyRef to avoid unnecessary interval teardown/restart on every edit/save cycle.
