   ## What
   Scan path member bytes before rune decoding when escaping is not needed.
   
   ## Why
   Most path members do not need escaping, so rune decoding adds unnecessary 
work.
   
   ## Implementation
   - Add an ASCII byte fast path.
   - Keep rune-aware escaping for quotes, backslashes, and control characters.
   
   ## Benchmark
   Apple M1 Pro, Go 1.26.3, darwin/arm64, GOMAXPROCS=1; median of 10 runs, 500 
ms each, compared with benchstat.
   
   | Workload | Before | After | Change |
   | --- | ---: | ---: | ---: |
   | Single field | 47.21 ns/op | 41.62 ns/op | 11.8% faster |
   | 64 fields | 2.281 µs/op | 1.752 µs/op | 23.2% faster |
   | Control-heavy | 1.043 µs/op | 1.054 µs/op | No significant change |
   
   Allocations are unchanged. Reproduce with:
   
   ```sh
   go test -run '^$' -bench '^BenchmarkNormalizeVariantPath$' -benchmem 
-count=10 -benchtime=500ms .
   ```
