Pi agent config backup

Private whitelist backup for global Pi configuration.

Backed up:

• settings.json, AGENTS.md, optional system/keybinding/model files
• mcp.json with environment-variable placeholders only
• extensions/, skills/, prompts/, themes/
• small backup/update helper scripts

Not backed up:

• sessions, package installs, caches, logs
• auth.json, mcp-oauth/, secrets/
• binaries in bin/

Local MCP secrets live in ~/.pi/agent/secrets/mcp.env and are loaded by the pi() shell function in ~/.zshrc.

Restore sketch:

npm install -g --ignore-scripts @earendil-works/pi-coding-agent
git clone https://github.com/ThePhoenixCoding/pi-agent-config.git ~/.pi/agent
pi update --extensions
pi
/login

Recreate local secrets manually in ~/.pi/agent/secrets/mcp.env.
