release: prepare Desktop 0.13.12 and Agent 0.13.3

Complete the pending Supervisor changes with opt-in execution, incremental automatic reviews, and activity history. Preserve saved preferences and plans, skip model calls for unchanged input, and keep full replay and cancellation limitations explicit. Update both release versions, bilingual notes, feature matrices, migration fixtures, and validation evidence. Clear stale browser errors after a successful close retry. Focused validation passed 690 tests across 35 files, plus notes verification, typecheck, and lint; full CI and native release acceptance remain pending. No local production build or packaging was run. Release note: Enable Supervisor to review work, trace story graphs, and inspect manual or automatic activity without repeating model calls for unchanged input. Desktop 0.13.12 and Agent 0.13.3 also prepare idle remote Runtime cleanup and retirement of replaced Agents; update Desktop before the Host environment. Database upgrades require a pre-upgrade backup for rollback.

 Do not use tools or external context. Return only JSON matching the output contract.
 Memory evidence is current background, not an event in the review interval. Its occurredAt is the actual last update time, not a historical content snapshot. Do not infer when its current content first became true or turn it into a historical event.
 Task status is current, not a snapshot at the review end. Use only supplied creation or completion timestamps within the review interval for task events.
+Automatic evidence can contain only a portion of a source (locator start/end). Describe only that portion; do not imply the entire source or interval was reviewed. Previous summaries and known entity descriptions are background, not new events.
 Use source reference IDs exactly as provided. Entity IDs are local to this output, not identities across runs.
 To identify an existing concept, set persistedId to an ID from KNOWN ENTITIES only. Omit persistedId for new concepts. Never infer persistent IDs from local IDs or labels.
