Commit Message

Add configuration validation

Implements Config.Validate() to catch invalid configuration at startup
instead of failing later with unclear errors.

Changes:
- Add Validate() method that validates all config fields
- Validate addresses: listen addresses allow wildcards, peer addresses reject them
- Validate numeric fields: MaxPeers, ExchangeInterval, DiscoveryInterval (allow 0, reject negative)
- Validate log level: debug, info, warn, warning, error (case-insensitive)
- Return all validation errors together using errors.Join()
- Call validation in main.go after CLI flag overrides

Test coverage:
- Valid configurations
- Invalid addresses (missing port, wildcards, empty host)
- Invalid numeric values (negative)
- Invalid log levels
- Multiple simultaneous errors
- Edge cases (empty optional fields, zero intervals, whitespace log levels)

Code quality:
- Extract helper methods to reduce cognitive complexity
- Use constants for test literals
- Add godoc to all validation methods
