Drag-select auto-copy, a flat type-to-filter model picker, install-aware upgrade
notices, quieter long-session compaction, and layout breathing room.

TUI

• Drag-select auto-copy. With mouse capture on (the default), finishing a
  drag selection in the transcript writes the selected text to the system
  clipboard on mouse-up. Highlight clears immediately; the status flash waits
  for the clipboard write (Copied … on success, Copy failed on error).
  Alt+C structured copy uses the same honesty. Alt+M still hands the mouse
  back for native terminal selection.
• Flat model picker. Choosing a model is one type-to-filter list of
  provider / model rows — no nested provider drill-down. Type to narrow,
  Enter selects; Alt+F still toggles favorites when wired.
• Install-aware upgrade notice. When a newer GitHub release exists, a
  non-blocking startup notice names the running and latest versions and the
  right upgrade step for Homebrew, source/Bun, deb, release binary, or
  unknown. Network and detection failures skip quietly.
• Bottom breathing room. The prompt box sits one blank row above the
  terminal's last line on tall enough terminals, so the layout no longer
  feels flush against the frame edge.
• User-message breathing room. Your turns in the transcript keep a blank
  bar row above and below the message text, so prompts are easier to spot
  while scrolling.
• Landing survives MCP connect failure. An MCP status failure still shows
  as a system notice and no longer wipes the mountain landing screen.

Session

• Quieter re-reads under compaction. When the same file is read more than
  once in a long session, older successful read_file results become a short
  stub and the newest stays whole, so context is not filled with duplicate
  file bodies. Chunked reads of different ranges stay distinct. Errors stay
  verbatim.
• Changelog watermark honesty. Upgrade notes are no longer marked as
  “already shown” when nothing was actually displayed.
