Manual Publish Only for Social Snippets - Plan

• Remove the scheduled trigger from .github/workflows/publish_social.yml.
• Keep the manual dispatch trigger and inputs intact.
• Update docs/self-hosted-social-runner.md to describe manual execution only.
• Update README.md, AGENTS.md, and GEMINI.md so the docs match the workflow.
• Validate the workflow YAML after the edits.
