v0.2.12

Changed

• Let deep railmux ssh history pages tolerate a small number of changing
  agent status rows while retaining strict pane, geometry, generation, and
  unique-anchor checks against unrelated or ambiguous content.
• Start a missing remote Railmux session for railmux ssh without the older
  tmux copy-mode scroll coalescer; the fast client's local history layer remains
  the sole owner of agent wheel input. Ordinary ssh followed by railmux is
  unchanged.
• Make the wheel smoke verifier discover both site-packages and Debian-style
  dist-packages, including pip's local/ prefix layout.

Fixed

• Retry a deep history page on a later upward wheel gesture when its response
  was lost under display backpressure, while rejecting any late response from
  the expired request.
• Invalidate stale agent history routes immediately when keyboard navigation
  in the Railmux sidebar or the default tmux prefix can switch the displayed
  session, without adding work to ordinary agent input or terminal focus
  reports.
• Forward vertical and horizontal wheel events on the compact status row
  without cancelling frozen agent history viewports; genuine status-row
  clicks continue to change pages normally.
