feat(ja-JP): add skill sub-reference translations (angular, remotion, etc.)
Translated 85 skill sub-reference files to achieve full parity with
the English source:
- skills/angular-developer/references/ — 35 files (all references)
- skills/remotion-video-creation/rules/ — 28 files (all rules)
- skills/tinystruct-patterns/references/ — 5 files
- skills/openclaw-persona-forge/references/ — 6 files
- skills/skill-comply/prompts/ — 3 files
- skills/lead-intelligence/agents/ — 4 files
- skills/brand-voice/references/ — 1 file
- skills/frontend-slides/ — 2 files
- hooks/memory-persistence/README.md — 1 file
English source parity: 0 missing files (excluding rules/zh/, internal
docs, and experimental examples absent from zh-CN)
