Publish v0.2.11 and document the host disk limit

- Pruned the superseded v0.2.0 and v0.2.9 releases through the API (~565 MB of
  assets) after the host root filesystem hit 100%, which blocked release uploads
  (HTTP 500 "no space left on device") and even git push ("unpacker error").
- Published v0.2.11 locally with the fixed script: all five artifacts verified on
  the release (Linux/Windows/macOS ports, NSIS installer, AppImage).
- TODO records the remaining ~150 MB headroom and the exact host cleanup commands;
  MEMORY and RELEASING describe the disk failure mode and the pruning.
