2c7bf2c932 Fix fuzzer-found bugs, add libFuzzer harness for v3 
Add tests/v3/fuzzer/ with libFuzzer harness covering all four parse
paths (auto-detect, JSON, GLB, float32 mode) with ASan+UBSan.

Fix two bugs found by 10+ hours of fuzzing (~23M iterations):

1. UB: (int64_t)inf in cj_parse_number when extreme exponents like
   22222222e222222 produce infinity. Add cj_dbl_to_i64() that clamps
   inf/NaN/out-of-range values before casting.

2. Null deref in tg3__parse_string when glTF array elements are not
   JSON objects (e.g. "scenes": [[3]]). Add is_object() validation
   in TG3__PARSE_ARRAY_SIMPLE and TG3__PARSE_ARRAY_IDX macros.

Verified clean: 5.8M additional runs with zero crashes after fixes.

2aeac50277 Add fast float parser and benchmark float-heavy scene 
Replace strtod() with Clinger's fast path in tinygltf_json.h for ~1.5x
faster JSON float parsing. The new parser accumulates all digits into a
uint64 mantissa and uses exact power-of-10 tables for conversion,
avoiding locale-dependent strtod for ~99% of JSON float values.

Add optional float32 parse mode (parse_float32 option) that parses JSON
floats at single precision — fewer significant digits needed, wider fast
path range. Breaks strict double-precision conformance but sufficient
for glTF data which is typically single-precision.

Benchmark additions:
- gen_synthetic: add float_heavy preset (~500MB ASCII float JSON)
- bench_v3: add --float32 flag for float32 parse mode benchmarking

78f4a5cfe8 Add tinygltf v3 single-header C API (tiny_gltf_v3.h) 
Ground-up C-centric rewrite of tinygltf with pure C POD structs,
arena-based memory management, structured error reporting, streaming
callbacks, and no STL dependency in the public API. Uses tinygltf_json.h
as the sole JSON backend.

Includes complete parser (JSON + GLB), writer (JSON + GLB), streaming
writer, C++ RAII wrappers, and C++20 coroutine facade. Verified with
Cube.gltf and Fox.glb parse/write round-trips.
