chore: remove zap compatibility layer

Removes zap.go which was a compatibility layer that was never used.
This eliminates go.uber.org/zap as a direct dependency.

Philosophy: ONE canonical way - NO adapters, NO compatibility layers.

fix: correct module path to luxfi/log

Update logger with geth-style API and GitHub Actions

- Update geth.go to use ctx ...any pattern for geth compatibility
- Update log/log.go with improved Logger interface and Field functions
- Add GitHub Actions workflows:
  - CI: tests, linting, benchmarks
  - Docs: GitHub Pages deployment
  - Release: auto-release on tags
- Add slog.go and zap.go adapters

Add short-form aliases and clean up terminology

- Add Str, Dur, AnErr as aliases for String, Duration, NamedErr
- Replace "zerolog" references with "logger" in code comments
- Update README terminology: "Chaining API" and "Traditional API"
- Keep external comparison to zerolog in README where appropriate

Initial logger package - high-performance zerolog-based logging

Features:
- Zero-allocation logging (~8ns/op, 0 allocs)
- Zerolog-style chaining API: log.Info().Str("k","v").Msg("m")
- Geth-style traditional API: logger.Info("m", logger.String("k","v"))
- Structured logging with type-safe field constructors
- Leveled logging (Trace, Debug, Info, Warn, Error, Fatal, Panic)
- Context injection via With()
- Pretty console output with colors
- Sampling and hooks support

Based on rs/zerolog with added geth-style API layer.
