fix(tui): render selected chat bubbles clearly

CHANGELOG.md

@@ -34,5 +34,6 @@
 - Bring shared TUI detail and sort behavior closer to `gitcrawl`: archives open newest-first, group count headers sort like `cnt*`, selected chat messages render before surrounding conversation context, document previews appear before metadata, and detail fields use `key: value` labels.
 - Keep split-width member tables readable by rendering compact dates instead of truncated ISO timestamps.
 - Prioritize gitcrawl-style footer muscle-memory controls in compact tmux panes before app-specific extras.
+- Render selected chat message bodies with the same transcript marker as their speaker line so detail panes read more like chat.
 - Force the Bubble Tea program to shut down on terminal signals so interrupted TUIs restore terminal modes and do not leave orphaned tmux panes.
 - Rename the public package nouns to `config`, `store`, `snapshot`, `mirror`, `state`, `output`, `tui`, and `cache`.
