feat(import): add Rust native parsing kernels for WeFlow and ChatLab JSON

Add @openchatlab/parser-native (napi-rs v3) with a shared byte-level JSON
scanner and two format kernels. Parsing large exports is 4-10x faster in
real-data benchmarks. The native module is an optional local build; the
pure-TS parsers remain as automatic fallback when it is unavailable,
disabled via CHATLAB_DISABLE_NATIVE_PERF=1, or rejects off-spec files.

The ChatLab kernel also parses the members array structurally, fixing the
TS head-regex heuristic that silently dropped avatars/roles for files with
nested arrays or long member lists.
