Adds the TUI half of the /rewind feature so the Ink terminal UI gets the same affordance as the prompt_toolkit CLI. Python side (tui_gateway/server.py): - /rewind added to _PENDING_INPUT_COMMANDS so slash.exec rejects it and the TUI falls through to command.dispatch (the only path with access to live session state + memory hooks). - New command.dispatch branch for name == "rewind": v1 auto-picks the most recent user turn (Claude-Code-style single- step undo), calls SessionDB.rewind_to_message, refreshes the in-memory history, fires _memory_manager.on_session_switch with rewound=True, and returns the new "prefill" payload. - A dedicated picker overlay (multi-step rewind) is tracked as a follow-up to #21910. TS side (ui-tui/src/): - New "prefill" variant on CommandDispatchResponse + asCommandDispatch validator. Mirrors "send" but does NOT auto-submit; the client drops the message into the composer for editing. - createSlashHandler renders the optional notice via sys() and calls ctx.composer.setInput(d.message), letting the user edit-and-resubmit the rewound turn — the core UX promised by the issue. Tests: - 7 new tui_gateway tests covering prefill payload shape, in-memory history truncation, DB soft-delete, memory-provider notification (rewound=True), busy-session refusal, missing-session error, and registry placement in _PENDING_INPUT_COMMANDS. - Extended asCommandDispatch vitest covering the new prefill variant (with + without notice, and rejection of malformed payloads). Out of scope for v1 (tracked as #21910 follow-up): - Dedicated picker overlay in Ink (the multi-step rewind UI). v1 auto- picks the most recent user turn, matching the most common case. - Gateway platforms (Telegram, Discord, etc.) — issue scopes v1 to CLI + TUI only.
