v1.1.0 — strict zero-skill routing

What changed

• Returns zero skills for trivial and unrelated prompts.
• Strict automatic routing selects at most one high-confidence skill.
• Explicit $skill-name requests still win.
• Portable agent-skill-route CLI for Codex, Claude Code, Hermes, and Giga/GG Coder.
• Neutral-install and routing tests in GitHub Actions.

Why it matters

The router no longer turns every prompt into hidden context. It adds context only when a relevant workflow skill is worth its token cost.

Verification

20 unit tests pass. Clean GG companion installation passes. Trivial prompts produce an empty router block.
