rstack-ecosystem-ci

Self-check for the rstack ecosystem CI framework. Audits the latest GitHub Actions runs of the six `*-ci-from-commit` workflows in `rstackjs/rstack-ecosystem-ci` and reports, in a Markdown table, whether each failure's root cause lives in the eco-ci framework / infra (signal is untrustworthy — fix this repo first) or in real upstream↔consumer business code (signal is trustworthy — the framework's job is done, regardless of whether the crash happened during vitest, build, install, or a prepare-lifecycle hook). Use this whenever the user asks to self-check, sanity-check, audit, or "see the health of" the rstack ecosystem CI, the latest `from-commit` runs, or anything along the lines of "did eco-ci actually run the suites" / "is eco-ci itself healthy" — even when the user does not name the workflows explicitly.
