Adds a top-level workflow block to .ciagent/config.json with the four
standing rules for v0.2+ and all future milestones:
1. no_hitl: true — full automation, no human-in-the-loop
2. merge_strategy — fast-forward or rebase-then-fast-forward only;
no merge-commit-no-ff, no squash
3. release_flow_per_phase: true — every phase tag produces a Gitea release
(already in .ciagent/RELEASE_POLICY.md, now
also enforced in config.json)
4. branching — main < milestone/<slug> < phase/<NN>-<slug>
phase branches FF into milestone;
milestone rebases onto main then FF.
