//! Skills system — filesystem-based progressive disclosure.
//!
//! Skills are discovered from:
//! 1. Project: `.claude/skills/*/SKILL.md`
//! 2. User: `~/.config/collet/skills/*/SKILL.md`
//!
//! Architecture (mirroring Claude's Agent Skills):
//! Level 1 — Metadata (YAML frontmatter): always loaded into system prompt (~100 tokens each)
//! Level 2 — Instructions (SKILL.md body): loaded on-demand when skill is invoked
//! Level 3 — Resources (referenced files, scripts): loaded as-needed by the agent
