docs(credo): echo the family belief on this surface

One belief across every tool, consolidated: CREDO.md mirrors the
canonical content-addressed text the Flywheel engine serves at
GET /api/credo; the README carries the short form.

+# The Credo
+
+One belief, held steady across every tool in the family. The canonical,
+content-addressed copy is served by the Flywheel engine at `GET /api/credo`;
+this file echoes it.
+
+Flywheel and its tool family hold one belief steady across every surface:
+
+1. Knowledge is an open surface for anyone who can attain the means;
+   we build to lower the means.
+2. The work speaks for itself: an external check decides acceptance;
+   never reputation, never the model.
+3. Every result carries a receipt a stranger can re-run.
+4. No claim without its interval; the honest null is a first-class result.
+5. Ownership is earned by comprehension: you own what you can review,
+   explain, and defend.
+6. Learning is woven into the work: every flagged gap is a lesson about
+   your own system.
+7. The badge and the contribution were bundled; we rebundle them around
+   the work, not the worker.
+
+Growth, learning, knowledge, application, ownership: in that order,
+for everyone.

+## What this believes
+
+This tool is one lane of a family that holds a single belief steady across
+every surface: knowledge open to anyone who can attain the means; acceptance
+decided by external checks, never reputation; every result re-runnable;
+honest nulls first-class; ownership earned by comprehension; learning woven
+into the work. The full text lives in [CREDO.md](CREDO.md).
