  1. perf: prefix trimming for >32 incomplete literals — Teddy instead of AC 

    When literal extraction produces >32 incomplete prefix literals (e.g.,
225 case-fold expanded variants), trim to 4-byte prefixes and deduplicate.
This reduces literal count to fit Teddy (≤32 patterns, SIMD fast) instead
of falling through to Aho-Corasick (slower sequential scan).

Skip for AllComplete literals (exact matches) — those go to Teddy/AC directly.

LangArena suspicious pattern:
- Before: 225 literals → AC prefilter → 117ms
- After: 17 literals → Teddy SIMD → 10.9ms (10.7x faster, 1.8x from Rust)
