v0.2.15.dev202607282

Added

• Make the bottom status bar actionable on tmux 3.4+: click the provider name
  to switch Mode, the layout glyph to rotate Layout, compact R/1/2 to
  change pages, or the right-side tip/info/warning/error text to copy its
  complete untruncated source.
• Show transient click confirmation without replacing the current sticky
  status message, and explain when a modal must be closed before Mode or
  Layout can change.

Fixed

• Restore agent-pane opening on Railmux's dedicated tmux server by carrying
  the exact inherited socket through nested attach instead of falling through
  to the user's default server.
• Reject a nested display client that exits during its startup settle, clean
  up dead remain-on-exit panes, and surface the exact transport failure
  reason while leaving the underlying agent session alive.
• Keep status clicks out of filter and rename editors by routing Mode and
  Layout through private function keys, and keep every user-range action
  within tmux's 15-byte limit so right-side copy works in real terminals.
• Add Mode and Layout controls to compact status bars, preserve readable
  compact error colours and exact right-message space, and reinstall the
  shared click binding safely when upgrading a live lease.
• Suppress the full-width Local session transcript is not available yet
  pseudo-status while a new Claude Code transcript has not written its first
  record.
