v2.39.3

Fixed

• run402 ci link github workflows now deploy in GitHub Actions. run402 deploy apply treated a CI runner's stdin (a FIFO/file) as a second manifest source alongside --manifest, so every generated OIDC workflow failed with BAD_USAGE: Only one deploy manifest source. Explicit --manifest / --spec / --dir now take precedence over incidental stdin; deploy apply with no source and no piped stdin is a clear error instead of a hang; and the generated workflow redirects < /dev/null so it works even on CLI versions predating this fix. (#441)

Internal

• Scaffold for a run402-hosted agent-docs site (docs.run402.com): deploy manifest, GitHub OIDC deploy workflow, agent-skills discovery-index generator, and the agent-docs-self-host OpenSpec change. (#438-#440)
• MCP docs: note `project_id` is optional on `run_sql` / `get_schema` / `rest_query`.
