pin collapse toggles to the status-bar screen edges + flip chevron live (T-294)

Two fixes to the just-shipped collapse toggles:
- They lived inside the centre StatusbarHost, so they shifted when a pane
  collapsed and the bar resized. Move them to the OUTER status-bar row ends
  (screen edges) so they stay put. StatusbarHost reverts to its prior layout.
- The toggle was a const widget that read isCollapsed in its own build; Flutter
  skips identical const children on rebuild, so the chevron never flipped. Pass
  collapsed/visible in from the parent's arrangement listener so it rebuilds and
  the chevron tracks the action direction. A 'flips live' test now guards it.

The terminal is retained only as a general IDE tool.
+
+Why:
+1. No cross-widget text selection/copy in clide''s native widgets today (regression vs a terminal).
+2. PTY/TUI rendering is the fragile, OS-variant part of the Claude pane.
+3. Claude Code''s experimental tmux team mode (lead + N teammates, each a tmux pane) is the flagship capability to surface as real GUI panels, not scraped TUI.
+
+Direction: run Claude headless in tmux; render its conversation natively from the transcript JSONL; lead panel (left, with composer) + teammate tiles (right) in a responsive auto-wrap grid (1->2->3 cols); team-meta sidebar with roster + token budget.
+
+Principle: Claude-centric first, CLI-first (D-6) a strong second. Accept isolated, version-pinned coupling to Claude Code internal contracts where it serves the Claude integration; preserve CLI/event surfaces where sensible.
+
+Acceptance: all child tickets done; D-record landed; Claude pane renders natively with working select+copy and no terminal; a tmux team surfaces as lead + auto-wrapping teammate tiles + meta sidebar; all fragile CC-internals parsing isolated and version-pinned.
