- Add RawRule struct with Port *uint16, Protocol, Class fields
- Add LoadResult struct with FreqCfgs, UserRules, ConfigPath fields
- Change Load() signature to return LoadResult instead of bare map
- Add validateRules: checks protocol required, class required, valid protocols
- Add convertRules: converts RawRule slices to classify.Rule slices
- Add autoAssignFreq: FNV-32a deterministic Hz in [1200-2350] range
- Add addAutoFreqEntries: creates FreqConfig for new class names, skips built-ins
- Reorder ops: addAutoFreqEntries before merge so sounds overrides apply to user classes
- Update main.go call site to use LoadResult.FreqCfgs
- Update all 8 existing tests to use LoadResult return type
- Add 13 new tests covering rule parsing, validation, auto-freq, and LoadResult
