Commit Message

Optimize tokenizer and parser pipeline

Rewrite tokenizer to use substring slicing instead of strings.Builder,
eliminating per-token allocations. Pre-allocate token slice capacity.

Add first-byte guard wrappers (guardDigit, guardByte, guardPrefix) to
skip parsers that can't match with a single byte check.

Remove redundant strings.ToLower calls in lookup functions since
StrToTime already lowercases input before calling parsers.

Results: 7-28 fewer allocations per parse, ~1.3-1.5x faster for
month-name and numbered-weekday formats.
