I'm Bonk, and I've done a quick review of your PR.

Adds byte_offset(), data(), as_slice(), as_mut_slice() methods to TypedArray locals, plus FromJS impls for Local<T> typed arrays. Overall well-structured with good test coverage.

Findings (highest severity first):

1. [MED] as_mut_slice safety comment understates the aliasing risk — two different Local handles can alias the same buffer memory.
2. [LOW] local_typed_array_byte_length is declared in FFI (C++, header, and Rust bridge) but never called from Rust — dead code.
