Release 0.6.1: install in Copilot CLI and Codex

Root plugin.json (Agent Plugins format) for Copilot CLI and Codex beside
.claude-plugin/plugin.json; SKILL.md finds the launcher without
CLAUDE_SKILL_DIR and uses commonplace.ps1 in PowerShell; the release ships
plugin.json and bumps both shelf marketplace lists.
