feat(agents): chat-style conversation view with folded tool runs, tags, jump-to-latest and retract (#2067)

* feat(agents): chat-style conversation view with folded tool runs, tags, jump-to-latest and retract (#1980)

- Lay the conversation out as chat: user messages on the right, agent replies on the left, each with an author row, a card, actions in the header and a time/duration footer.
- Fold consecutive reasoning and finished tool calls into one collapsible 'Reasoning - N tool calls' row with +added / -removed counts; running tools stay expanded.
- Render @file and /skill references in message text as distinct tags.
- Load earlier entries in batches without moving the viewport, offer 'Jump to Latest' when scrolled away, and defer loading while the scrollbar is dragged.
- Add 'Retract Message': stop the agent, drop that turn and every later one, and put the original text/images back in the composer.
- Drop the catalog entry for the replaced duration tooltip.

* fix(agents): preserve conversation scrolling and retract state
