workstation: agent-driven contribute flow for non-technical users [ci skip]

emo can't use git — his agent must do all VCS mechanics invisibly.
Managed claudeMd (every session, top precedence) now instructs agents:
commit -> push <os-user>/<topic> branch -> open PR via Forgejo API
(user's PAT from ~/.git-credentials) -> back to clean master -> tell
the user in plain words it's submitted for review. AGENTS.md carries
the full recipe with the curl call.

Verified live as emo: PR #1 opened (HTTP 201, write:repository scope
suffices) and closed via his PAT. Deployed to
/etc/claude-code/managed-settings.json; codex AGENTS.md mirrors for
emo + ancamilea regenerated from the new claudeMd.

When you finish a change in ~/code: commit it, push to a branch named <os-user>/<short-topic> on the forgejo remote, open a PR to master via the Forgejo API (token = the password field in ~/.git-credentials), then check out clean master again so background auto-refresh keeps working. Tell the user in plain words that the change is submitted for Viktor's review. Direct pushes to master are rejected (branch protection).
