Workspace in read-only mode — please run garbage collection after history rewrite

Hi, our workspace REDACTED has been placed in read-only mode for exceeding the 1 GB Free plan limit. We are on the Free plan, so following the guidance in previous threads I'm posting here rather than opening a ticket.

We have already reduced the repository REDACTED/REDACTED: we ran git filter-repo to purge large binaries (.glb models, video, OBB and an SDK tool) from the entire history, and force-pushed all rewritten refs (dev, master, tags v0.2.0 and v0.7.0).

A fresh git clone --mirror of the remote now packs to 86.19 MiB, down from ~1.5 GB, which confirms the reachable content is already reduced. The reported size still reflects unreachable objects left over from the rewrite.

Could someone please trigger garbage collection manually on this repository so the space is reclaimed and the workspace returns to read-write? Thanks!
