Implement Phase 1 tasks 1.1-1.4 (scaffold + core shell + Teltonika framing)

- Project scaffold (Node 22 + TS 5 + pnpm + vitest + ESLint flat config)
- Core shell: TCP server, session loop, adapter registry, types
- Configuration (zod-validated env) and pino logger
- Teltonika adapter: IMEI handshake, frame envelope, CRC-16/IBM,
  codec dispatch registry, DeviceAuthority seam (AllowAllAuthority default)

Codec data parsers (1.5-1.7), Redis publisher (1.8), and downstream
tasks remain. 36 tests covering CRC, framing, handshake, device
authority, config, and core server. typecheck/lint/test/build all clean.
