Summary

JsonRpcTransport: httpx-based sync JSON-RPC client with retries (exponential backoff) for transient failures, no retry on non-retryable 4xx
Typed exception hierarchy (AlchemyError, AlchemyHttpError, AlchemyRpcError, AlchemyTimeoutError)
JSON-RPC request/response/error dataclasses in models.py
Full respx-mocked test suite (11 new tests), no live network calls

Verified locally: hatch run lint, hatch run format-check, hatch run test (17 passed), hatch build.

Closes #3

Note: merges into develop, not the default branch main — issue closed manually after merge per repo process.
