- pool: SearchTask + FindSubstring (case-insensitive substring scan with
query generation for stale-result dropping)
- editor: FindState on EditorState; find bar handlers (ToggleFind/FindNext/
FindPrev/FindClose); worker-pool scan of the in-memory content; edit-aware
offset remapping (shift after, drop overlapping); next/prev with
wrap-around, selection + scroll to match; main-owned find_bar input
forwarded via FindQueryChan (browser search_bar precedent)
- ui: find-bar layout below the margin-free top bar; search icon on the top
bar right; new search/close/chevron_up/chevron_down icons
- logic: findQueryChan, TypeSearch result handling, findReset on open
- frame: FindQuery field (main syncs the widget text like Query)
- tests: pool scan tests, find-state unit tests (remap, nav, gen gate,
focus), e2e find bar + navigation + edit-survival on real files
- docs: spec/architecture/development_plan updated (search implemented,
channel/task tables)
