Add a dependency-light TypeScript ONP/1 client for Node.js backends

[devkyato]

Goal

Add a TypeScript client that lets Node.js backend services exchange ONP/1 frames with the existing Python and ESP32 implementations.

Scope

• Node.js 20+ TCP/TLS client.
• Strict frame parsing with the 16 MiB protocol ceiling and a configurable lower limit.
• Buffer, UTF-8, JSON, bigint/int64, number/float64, boolean, and null values.
• ACK, PING/PONG, CLOSE, message ID rollover, and duplicate behavior.
• AbortSignal-aware connect/send/receive operations.
• ESM and CommonJS-compatible package output if this can be achieved without duplicate APIs.

Acceptance criteria

• Consumes the fixed vectors in python/tests/test_protocol.py.
• Live integration tests against the Python server.
• Corrupt CRC, truncated frame, oversized declaration, invalid UTF-8, and reconnect tests.
• Typed public API documentation and a runnable VS Code example.
• No compatibility or benchmark claims without recorded results.
