fix(types): add missing types and fix compilation errors - WIP

Fixed compilation errors in integration code:

Type System Fixes:
- Add types.Logger type alias (*slog.Logger)
- Add PoolInfo.LiquidityUSD field
- Add ProtocolSushiSwap and ProtocolCamelot constants
- Fix time.Now() call in arbiscan_validator.go

Pool Discovery Fixes:
- Change cache from *cache.PoolCache to cache.PoolCache (interface)
- Add context.Context parameters to cache.Add() and cache.Count() calls
- Fix protocol type from string to ProtocolType

Docker Fixes:
- Add .dockerignore to exclude test files and docs
- Add go mod tidy step in Dockerfile
- Add //go:build examples tag to example_usage.go

Still Remaining:
- Arbitrage package needs similar interface fixes
- SwapEvent.TokenIn/TokenOut field name issues
- More cache interface method calls need context

Progress: Parser and pool discovery packages now compile correctly.
Integration code (main.go, sequencer, pools) partially working.
