When a deep directory was renamed or deleted externally and both the
directory itself and a parent directory were cached, only the self entry
was cleared — leaving the parent's children list holding a ghost reference
to the old child. Walk up to the nearest cached ancestor in addition to
the direct hit so both stale entries are dropped together.
Also gate the follow-up getFileTree refetch on the directory still being
expanded. Collapsed branches only need their cache cleared; they will
re-hydrate naturally on the next expansion, which avoids unnecessary IPC
traffic during FS event bursts.
Deep directories (beyond the workspace snapshot's depth limit) relied on
a lazy-loaded override cache that was never invalidated, so agent-created
files, in-app deletes / renames / rollbacks, and external changes inside
expanded deep folders stayed invisible until the folder was reopened.
Propagate watcher `changed_paths` through the delta envelope and fire a
Meta event whenever FS activity doesn't alter the tree/git snapshots, so
the frontend can surgically invalidate affected cache entries and
re-fetch. Manual refresh (Reload from disk) clears the cache and
re-hydrates still-expanded deep dirs through the same path. Replayed
deltas after reconnect are forwarded to the same listeners.
Also split the combined workspace-state effect into tree / git / status
slices so unrelated state transitions (e.g. the 'resyncing' flip during
a refresh) no longer rebuild the entire node tree and cause a flash.
Gate git refresh on .git presence so file churn in non-git workspaces no longer produces endless resync_hint events, and silently log tree/git refresh errors during watch flushing instead of flagging requires_resync, which turned transient failures into self-reinforcing loops.
Degrade gracefully when the filesystem watcher fails to attach (e.g. permission denied, inotify quota): keep the initial snapshot, surface a degraded flag, and expose a store-level restart that the banner uses to retry attachment after the root cause is fixed.
Propagate is_git_repo through the snapshot so the git log and changes tabs render a dedicated "Not a Git repository" empty state instead of raw git stderr with a useless retry button.
Stop polling get_git_branch from the title bar once it returns null and re-arm on visibility change.
Add translations for the new banner, empty-state, and retry keys across all ten locales.
Introduce a shared workspace-state backend stream with snapshot/delta APIs for file tree and git changes.
Migrate both aux panels to a common frontend workspace store with lifecycle-safe stream handling.
Apply batched watch throttling, path-aware git refresh gating, no-op delta suppression, and bounded history compaction to improve runtime stability.
Ensure async watch setup is safely discarded after effect cleanup.
Use idempotent watcher release logic to avoid duplicate subscriptions and unbalanced stop calls.
Add .scrollbar-thin and .scrollbar-thin-edge utility classes in
globals.css and apply them to sidebar, file tree, git changes,
git log, session files, diff preview, and message thread panels.
Replace scattered inline webkit-scrollbar overrides with the
shared classes for consistent appearance and gutter behavior.

Support typing "@" in the chat input to trigger a file list popup with
filtering, keyboard navigation, and file/directory attachment. Directories
from the sidebar file tree now attach as resource links instead of injecting
text into the input.
