Summary
Extends the no-torch rule to detect programmatic torch mode enablement via HTML5 MediaTrackConstraints (in addition to the existing React Native react-native-torch detection).
Changes
Rule logic (eslint-plugin/lib/rules/no-torch.js):
Added detection for track.applyConstraints({ advanced: [{ torch: ... }] }) calls
Extracted helper functions to module level for clarity and reusability
Maintains existing React Native torch import detection
Unit tests (eslint-plugin/tests/lib/rules/no-torch.test.js):
Added 3 new invalid cases covering HTML5 Web API usage (torch: true, torch: false, mixed constraints)
Added 3 new valid cases to prevent false positives (no torch, empty advanced, non-torch constraints)
Updated ecmaVersion for consistency with existing tests
Documentation (eslint-plugin/docs/rules/no-torch.md):
Added "React Native" section for existing detection
Added "HTML5 Web API (MediaTrackConstraints)" section with non-compliant and compliant examples
Added MDN reference for MediaTrackConstraints
E2E test (test-project/src/no-torch.js):
Added Web API example function showing both compliant and non-compliant patterns
Organized examples with section comments
Changelog: Updated [Unreleased] section under Changed
Testing
All 19 existing unit tests pass ✅
New tests cover both valid and invalid HTML5 Web API patterns ✅
Code style aligned with project conventions (module-level constants and helpers) ✅
