v0.1.19

Added

• okf install [agent] — unified agent setup. Install integration for Claude Code, OpenCode, Copilot, Cursor, Windsurf, or Cline with a single command. Replaces okf install-skill.
• Bumblebee supply-chain scan — pre-commit hook (.pre-commit-config.yaml) and CI job scans dependencies for known compromises via bumblebee scan --findings-only.
• AI agent instructions made forceful: AGENTS.md and .github/copilot-instructions.md now lead with "CRITICAL RULE: Never grep source files first, always run okf lookup".
• AI-assisted pre-release audit section in RELEASE.md.

Changed

• .github/copilot-instructions.md — detailed lookup patterns for Copilot users.
• README: unified "Agent Installation" section replacing "Claude Skill" section.
