Release v2.9.0

Added

• cratis init now configures Pi, writing the Chronicle skill to .pi/skills/chronicle-cli/SKILL.md, the diagnose prompt to .pi/prompts/, and the @CHRONICLE.md reference to AGENTS.md. Pi is detected from a project's .pi/ directory and from the PI_* variables it exports, so running cratis init inside a Pi session configures it even on a project that has nothing yet. --tool pi targets it explicitly. (#79)

Changed

• cratis init now reports when CHRONICLE.md was generated by a different version of the CLI, and names cratis init --refresh as the fix. The embedded command catalog is a snapshot rather than a live lookup, so after an upgrade it kept describing the surface it was generated from — commands added since were invisible to an agent, and ones renamed or removed were still advertised, with nothing saying so. (#79)
• cratis init --refresh now also updates the Pi skill, alongside the Claude and Copilot ones. (#79)
