feat: implement Polygon RPC client with caching and rate limiting (#8)

## Summary
- Add PolygonClient for blockchain data queries with rate limiting, retry logic, and Redis caching
- Implement Transaction and WalletInfo data models with unit conversions
- Add comprehensive test coverage (51 tests)

## Features
- Token bucket rate limiter to respect RPC provider limits
- Exponential backoff retry logic with configurable attempts
- Automatic failover to secondary RPC URL
- Redis caching with configurable TTL
- Methods: get_transaction_count, get_balance, get_token_balance, get_block, get_wallet_info

## Test plan
- [x] All 51 profiler tests pass
- [x] Ruff lint passes
- [x] Mypy type check passes

Closes #8
