provision-agent.py — Playwright automation for AI agent identity provisioning.

Enrolls AI agent identities in Cloudron, logs into Gitea/Discourse/Redmine via
SSO, generates API keys, and stores all credentials in Bitwarden.

Usage:
    python3 provision-agent.py                       # provision all agents in manifest
    python3 provision-agent.py --agent vp-techops    # provision one agent
    python3 provision-agent.py --phase1-only         # Cloudron enrollment only
    python3 provision-agent.py --dry-run             # validate manifest without browser

Manifest: agents.yaml (see agents.yaml.example)

See: ~/Q3/agent-identity-bootstrap.md for the full architecture.
