## What changed
- Add incremental, case-insensitive literal search across transcript details, loading older history as needed. Use `F3` to start Find, or `/` in the transcript pager, and navigate matches in either direction. Closing Find restores the previous presentation and reading position.
- Add clickable activity detail controls and `F4` keyboard focus for inspecting individual activity groups in the owned transcript. Preserve expansion state as live activity becomes history.
- Expose configurable `global.find_transcript`, `global.focus_activity`, and `pager.find` bindings under `tui.keymap`. Let new defaults yield to existing custom bindings and show available completions for pending chords.
## Testing
Add regression coverage for Unicode matching, bounded scanning, paginated and changing history, selection during search, composer input isolation, activity controls, and custom shortcut conflicts.

## Why
Composer drafts include attachments, mention targets, and deferred paste payloads in addition to visible text. Vim undo needs to restore that complete state as a single edit.
## What changed
- Add bounded, draft-level Vim undo history, with `u` as the configurable default binding in normal mode.
- Group complete Vim commands and insert sessions into undo steps, including direct composer changes such as pastes and attachments.
- Preserve undo, repeat, and search state when a reverse-history preview is canceled, and start fresh history when another prompt is accepted.
## Testing
- Cover grouped edits, custom bindings, history and search interactions, attachments, and large paste payloads.

## What changed
- Add draft-local forward and backward literal search with `/` and `?`, plus
wrapped repeat navigation with `n` and `N`.
- Support search motions after delete, change, and yank operators, while keeping
queries separate from the draft and skipping atomic elements and partial
grapheme matches.
- Render and edit the query in the composer footer, highlight matches, and add
configurable `tui.keymap.vim_search` bindings to the keymap picker and schema.
## Testing
- Cover navigation, wrapping, operator composition, repeat behavior, Unicode
graphemes, atomic elements, query editing, paste handling, and rendering.
