v0.4.1 — Auth docs cleanup
Changes
- User guide authentication section is now instrument-agnostic — no instrument-specific references or URLs
- Documents the two credential patterns clearly:
- Static string — for long-lived registration secrets
- Callable — for short-lived tokens that need refreshing before the 24h HelixObs JWT renewal
No code changes. Upgrade from v0.4.0 only needed if you rely on the user guide.
