v5.27.8 — sidebar Tuning link scroll fix

Platform-only patch release. No SDK source change — the Node + Python SDKs are intentionally not republished (registries stay at their last SDK release).

Fixed

• The sidebar Tuning link now works when you're already on /policies#calibration. Tuning is a same-page hash link, and the browser only scrolls on a hash change — with #calibration already in the URL a click was a genuine no-op (the calibration section's own scroll effect fires once at first data load, never on click). The nav click handler now detects a same-page hash link and scrolls the target section into view itself; cross-page navigation is unchanged.
• Self-host consoles no longer show a red 404 on every dashboard page. GET /api/hosted/claim returned 404 when DASHCLAW_HOSTED is off, but ClaimWorkspaceBanner probes it on every page; GET now returns the same calm 200 non-claimable preview used for the no-cookie case ({claimable: false, reason: 'not_hosted'}). POST stays 404 off-hosted.
