v0.4.2

json v0.4.2 moves the library to Mojo 1.2.0 and MAX 26.7.

• The Mojo pin is now >=1.2.0,<2.0.0.
• max-core stays optional (GPU path only) and is constrained to ==26.7.
• mojodoc is pinned to v0.1.2 and mozz to v0.2.2.
• CI uses prefix-dev/setup-pixi v0.11.2 with pixi v0.83.0.
• Mojo 1.2 fixes: std.hashlib is now std.hash; CStringSpan.ptr() no longer compiles, so the nul-terminated call sites (strtod and the simdjson parse) take the pointer from the String; and the no-op ^ transfers that Mojo 1.2 warns about are gone, so warnings-check is clean.
• Includes the parsing performance work merged since v0.4.1: tape strings are serialized and keys matched without allocating, the tape is built in one FFI call on a per-thread parser, and the tape symbols are resolved once per process.

There are no API changes.
