Precompute OR of all sort keys; a byte position that is zero across every
key contributes a no-op pass. Default two-criteria setup leaves the low 32
bits zero, so 4 of 8 passes are skipped without a histogram scan. 2x on the
sort, 3-8% on high-match queries. No regression when all bytes are used.

------
- Up to 2x faster matching for single-character queries
- Single-character queries are up to 2.4x faster
- This is the most latency-sensitive case; the first keystroke scans the entire list before the result cache can help
- Faster sorting of search results; the default two-criteria ranking skips redundant radix passes
- Fixed nondeterministic match highlight positions
- fzf now detects terminal resize on Windows in `--height` mode (#4790) (@Cyrus580529)
- Fixed signal handler cleanup when fzf is used as a library; SIGINT/SIGTERM/SIGHUP and resize handlers no longer persist after `Run()` returns
