feat: add binary type support for host functions

Adds Uint8Array/Buffer support for host function arguments and returns.

Architecture:
- New hyperlight-js-common crate: shared wire-format constants, binary
  sidecar encode/decode, FnReturn enum, DecodeError type
- Guest extracts Uint8Array from QuickJS VM into binary sidecar
- Host dispatches via register() (typed serde) or register_js() (JS bridge)
- NAPI layer creates native Node.js Buffers via C API (no base64)
- Tagged return format (0x00=JSON, 0x01=binary) for return path

Key changes:
- Single CallHostJsFunction entry point (removed legacy JSON-only path)
- Native Buffer marshalling in NAPI (JsArg/JsReturn types)
- Depth limits on all recursive JSON tree traversals (MAX_JSON_DEPTH=64)
- Trailing data rejection in sidecar decoder
- Typed register() rejects binary args with clear error message
- Comprehensive test coverage (Rust unit + integration + JS vitest)
- Updated README with Binary Data section and wire protocol docs
- Updated CI publish order for new common crate
