/**
 * V2 SAFE Stack — Claude Code Skills mechanism (PRD §2.3, item 2).
 *
 * Writes a V2 unified SkillFM skill at the Anthropic Claude Code skill path:
 *   ~/.claude/skills/skillfm/SKILL.md
 *
 * Phase 1.5 真 binary verify: Claude Code's skillDescriptionCharCap = 1536
 * (not 8000 as Phase 1B docs claimed). The frontmatter `description` field
 * is what Claude Code shows when matching user prompts to skills, so it must
 * fit the 1536 cap or the agent will see a truncated trigger profile.
 *
 * Coexistence with existing skillfm-bso (BSO M9):
 *   - ~/.claude/skills/skillfm-bso/SKILL.md   ← BSO M9 brain_run hint (existing)
 *   - ~/.claude/skills/skillfm/SKILL.md       ← V2 unified Beacon (this module)
 * Both auto-load on Claude Code session start; redundancy is intentional.
 *
 * Format: Anthropic Skills standard (YAML frontmatter + Markdown body).
 * Refs:
 *   - https://docs.anthropic.com/claude/docs/skills (Skills format)
 *   - PRD-SAFE-V2.md §2.3 (L1 Claude Code, item 2)
