Backport v2-dev improvements to v1 (#647)

## Summary

Backports non-breaking improvements from the v2-dev branch to main. The
v2 model changes (Parakeet STT, Pocket TTS) are excluded since they have
quality issues; only bug fixes, code quality improvements, and feature
enhancements are included.

### Changes

- **Tooling**: Update Go directive to 1.26.0, golangci-lint to v2.11.3
- **Lint fixes**: Preallocate slices, remove deprecated `HasAnyTag()`
- **Wideband constant**: Extract 16kHz sample rate to
`pkg/pcm/rate.Wideband`
- **numwords fork**: Switch to `dharmab/numwords` with configurable
fraction/article/second parsing
- **Callsign parsing**: Add digit homophones (won→1, to→2, free→3,
for→4, ate→8, niner→9), ordinal stripping (1st→1), STT stutter
deduplication (eagle eagle→eagle), ~40 new bogey dope garble entries
- **Trackfile fix**: Fix heading double-conversion bug in `Course()` +
comprehensive test suite
- **Radar improvement**: Interpolate group track from all contacts using
circular mean instead of first contact only; report unknown track when
contacts diverge >90 degrees
- **SRS protocol**: Nil-safe `Client` field in `Message` type,
copy-by-value fix in `newMessage()`

### Not included from v2-dev
- Parakeet/Pocket model changes
- Model download infrastructure
- CLI/config interface changes
- Whisper/Piper/macOS TTS removal
- minRxDuration reduction (still needed at 1s for Whisper)

## Test plan
- [x] `make lint` - 0 issues
- [x] `make vet` - passes
- [x] `make test` - 942 tests pass
- [x] `go mod tidy && git diff --exit-code` - clean
