With the tokenizer reassembling split CSI sequences across a flush (prior
commit), no SGR mouse fragment can reach a text token anymore — terminals
write a mouse report as one atomic sequence, and any read/flush split now
re-joins in the tokenizer buffer instead of leaking. That makes the whole
downstream recovery layer dead code:
- SGR_MOUSE_FRAGMENT_RE, MOUSE_BURST_NOISE_RE, MOUSE_BURST_RESIDUE_RE
- parseTextWithSgrMouseFragments / parseSgrMouseFragment /
normalizeSgrMouseFragment
- the whole-text mouse-burst noise fast path in parseMultipleKeypresses
Remove all of it (~185 lines) and the tests that only exercised it. The
narrow legacy X10 wheel-tail resynth stays (distinct mechanism, kept with
its own test). This retires the #17701 → #18113 → #26781 → #28463 → #35512
regex hardening chain in favor of the one correct parser fix.
