Priority matchers on REAL C prompt strings (docs/05 §12.4), not mock phrasing. Sticky TABLE_* (#93). “remove last sheet” is info-only, state unchanged.

No s/u. If a back-strip control is needed later, map to real keys (f/b/n) after reading fork chartread.c — new ticket, not this one.
XY cancel: q\n, ~500ms, kill.
CI must run bundled chartread.mock.
Port the 39 legacy classifier cases + real-prompt fixtures.
