perf: optimize schema evolution mode performance

[chaokunyang]

Why?

Improve schema evolution/compatible mode throughput by reducing type-meta lookup overhead and enabling fast-path reads when schemas match, and extend benchmarks to cover list workloads.

What does this PR do?

• C++: optimize compatible-mode type-meta sharing/caching and add a fast-path struct read when schema hashes match; align benchmarks with field tags and compatible mode.
• Go: speed up compatible-mode type-meta sharing (uintptr key + first-type fast path), cache TypeInfo for struct/pointer fields and typedefs, and extend benchmarks/reporting for list workloads.
• Rust: add schema hash and fast type/meta lookup caches, use a faster vec reader and type-info path, and tag benchmark models + add a benchmark runner script.
