🤖 Augment PR Summary

Summary: This PR introduces a fast helper for comparing JSON Pointer property tokens against an external string by leveraging the token’s precomputed property hash.

Changes:

Added Pointer::Token::property_equals(value, value_hash) to perform hash-first comparisons and avoid full string compares when the underlying property hash is “perfect”.
Updated GenericToken::operator== to treat perfect-hash property tokens that differ only by trailing NUL bytes as not equal by additionally checking string length.
Extended the JSON Pointer token test suite with coverage for short/long property equality, trailing-NUL edge cases, and imperfect-hash collision behavior.
Added tests ensuring property_equals works for both owning (Pointer) and non-owning (WeakPointer) tokens.

Technical Notes: The new logic mirrors the existing object-key hash strategy: perfect hashes encode bytes but not length, so a size check is used to disambiguate cases like "a" vs "a\0" without paying for a full string comparison.
