v2.62.1

Two correctness fixes for real-world project/DRP layouts. No new tool surface; default behavior is unchanged.

Fixed

• Timeline archiving survives out-of-band archive names — the archive version counter was sourced solely from the local brain DB, so any <name>_archived_vNN timeline the DB hadn't recorded (another session/machine, or a crash between DuplicateTimeline and the version INSERT) collided on the next archive: DuplicateTimeline failed and Resolve raised a blocking "Unable to Rename Timeline" modal that wedged the UI. archive_current_timeline now scans every existing _archived_vNN suffix in the project and treats the DB counter as a floor, not the source of truth.
• inject_grades handles the SeqContainer/<uuid>.xml folder layout — listSeqContainerEntries only matched the legacy flat SeqContainer<N>.xml naming, so inject_grades threw No SeqContainer*.xml found on DRPs using the SeqContainer/<uuid>.xml folder layout that Resolve 19 exports (the same layout the grade-node extractor already handles). Both shapes are now matched.

Validation

• Static checks (import, API parity, api-limitations drift, agent-rules drift, doc tool counts, undefined-name and action-list guards) and focused unit tests (tests.test_timeline_versioning, tests.test_import_from_drp) run green.
• The DRP fix is offline zip surgery requiring no Resolve. The archiving fix is defensive counter logic covered by unit tests; no separate live Resolve run was required.
