/**
* The replay half of the strip parity triangle: what `_handleTerminalOutput` (session.ts)
* removes from the live stream, removed again from a stored buffer before it is replayed,
* because a buffer recorded before the live-side strip existed (or by an older server)
* still carries the sequences, and one replayed enable is enough to re-park xterm.
*
* - `strip-full` (claude/codex/gemini): alt-screen toggles, `3J` and mouse DECSETs.
* xterm obeys the toggles by switching to its scrollback-less alt buffer and wiping
* saved lines, so history disappeared on tab switch.
* - `strip-mux-and-mouse` (opencode, tmux-backed): alt-screen toggles and mouse DECSETs.
* A replayed tracking enable parks xterm in report mode, where a drag goes to the CLI
* instead of selecting text (and Ctrl+C without a selection is opencode's app_exit).
* `3J` stays: a TUI is not a `clear` consumer.
* - every other mode, tmux-backed: tmux's own client smcup only (#205).
*
* Exported so the parity with the live strip is a test (claude-scrollback-strip.test.ts).
