feat(gitea): add gitea-orchestrate agent-facing dispatcher

Adds the deterministic, agent-facing counterpart to gitea-workflow per
docs/adr/0011-gitea-skill-deep-modules.md, mirroring git-orchestrate's
shape: structured request/response JSON, safety gates on destructive
ops (delete-branch/release/tag/label/milestone/file, merge-pr), and
routing across the six gitea domain skills without conversational
disambiguation. Authored via kyberforge:agent-author directly (not
forge) since the artifact type was already known, and validated clean
via kyberforge:agent-audit (structure, provenance, and qualitative
checks all pass). Bumps plugin version 1.2.0 -> 1.3.0 in both manifests.
