l0ng-ai fae63aa2bc fix(terminal): clear the other anchored state when the scrollback goes
Removing the mark store took `marks().clear()` off `clear_scrollback`, which
left that path with no anchored-state invalidation at all — and it never had
any for the second store that needs it. Kitty image placements are anchored to
an absolute scrollback row, so purging the history moves every anchor: the
frame either paints over unrelated text or resolves past the viewport and
disappears, with no redraw coming since the daemon does not replay out-of-band
image frames. Clear the store, exactly as the reattach path already does.

Route the purge through `Term::clear_screen(ClearMode::Saved)` while here.
Reaching for `grid_mut().clear_history()` skipped the selection invalidation
alacritty does there, so a selection anchored in the discarded rows survived,
clamped onto the viewport, and copied whatever text had moved into it.

Also collapse `Cut`, now a single-variant enum around `CursorCut`, and repoint
the `memchr` comment at the scanner that still uses it. The image module's
anchor note now records the alt-screen caveat: an anchor read off the alt grid
resolves against the primary one, which wants a per-screen store to fix and is
left alone here.

Why

  • Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
  • Editor-grade input — suggestions, completion, highlighting, history search
  • Remote development — files, repos, panes, and git data stay on the remote machine
  • Native SSH — profiles, SFTP, port forwarding, and jump hosts
  • Agent-aware — Claude Code, Codex & co.: status, notifications, git context
  • CLI + Skills — agents create panes, run commands, and inspect output
