openplanr 2.1.0

Generate an ## OpenPlanr capabilities section into CLAUDE.md and AGENTS.md listing every skill with its triggers (and the delegated agents for Claude Code), and add the planr-openplanr router skill that picks the best OpenPlanr skill for a request.

Reconcile openplanr upgrade status against the npm registry's published CLI and the pipeline it bundles instead of the retired marketplace manifest, and report a leftover legacy host plugin as the incompatibility.
