feat: add support for PI coding agent

isanchez31 · claude · commit b718fcbc8dd1 · 2026-02-28T06:54:49.000Z
Add PI as a supported AI coding agent across all Spec Kit components:
- AGENT_CONFIG and AGENT_CONFIGS entries with .pi/skills/ directory structure
- Bash and PowerShell update-agent-context scripts
- Release packaging scripts (sh and ps1)
- GitHub release script zip entries
- README.md supported agents table and CLI reference
- AGENTS.md agents table
- Devcontainer post-create.sh CLI installation
