chore(embedded): cut v0.0.27-beta

Two exports for two different consumers were both just "Export". Name them:
- Classification (header, AI round-trip): "Export for editing" / "Import edits"
  — a filename-per-file JSON with no scanned tree, meant to be hand/AI-edited
  and re-imported. Download suffix is now .zddc-classification.json.
- Workspace (welcome screen, transfer/backup): "Import workspace" + a row
  "Export" tooltip spelling out it carries the snapshot + classifications for
  moving between browsers. Download suffix stays .zddc-workspace.json.
Each tooltip points at the other so they're not confused.

Also wire workspace.activeName (referenced by the dataset export but never
exported), so a classification file is named after its workspace.
