* feat(orcad-migration): unsaved drafts stay on this desktop and are renamed to the server on commit
* fix(orcad-migration): refuse clashing drafts from the rename's own collection; stricter live spec
* fix(orcad-migration): stamp renamed drafts with the server, rename at startup after a cut-off commit, keep draft refusals
* fix(orcad-migration): retain only after a startup rename is durable; startup survives an unreadable journal
* fix(orcad-migration): a cut-off commit is renamed and retained at startup, so the rename runs once
* fix(orcad-migration): one retain per migration at a time; no rollback that could drop newer edits
* test(e2e): check the visible draft in whichever editor a large file opens in
* fix(orcad-migration): startup retains only migrations of hosts this profile owns
* ci(e2e): route the editor-drafts migration spec to the sources it covers
