Function evaluateSafety

evaluateSafety(q: SafetyQuery): SafetyResult
Evaluate the safety of placing a candidate pitch in a voice.

Reasons are merged from harmonic context (chord tone / tension / avoid / scale) and counterpoint (vertical dissonance, parallels, voice crossing). The strict profile treats avoid notes and parallels as dissonant; pop treats them as warnings. The final verdict is the worst severity among the reasons.
Parameters
- q: SafetyQuery
  The candidate and its harmonic/voice-leading context.
Returns SafetyResult
The verdict, reason bitmask, and optional resolution guidance.
Example
```
import { evaluateSafety, makeChord, majorKey, NoteSafety } from '@libraz/libcantus';
const result = evaluateSafety({
  profile: 'pop',
  candidatePitch: 60, // C over a C major chord
  chord: makeChord(0, 'maj'),
  key: majorKey(0),
  otherVoices: [],
  strongBeat: true,
});
result.safety === NoteSafety.Safe; // true — C is a chord tone
```
