Deep string equality: compare actual string content, not NanValue bits. Handles both inline short strings and arena-allocated strings.

pub fn bits(self) -> u64

Raw bits - useful for using as HashMap key (inline values only).

pub fn from_bits(bits: u64) -> Self

pub fn map_key_hash(self, arena: &Arena) -> u64

Content-based hash for use as map key. For inline values (int, float, bool), uses bits(). For arena-backed strings, hashes the string content so that two NanValues for the same string content produce the same key regardless of arena index.
