merge: retain published Desktop 0.13.13 history

Merge the published release preparation commit without rewriting either
branch. Keep the approved Desktop 0.13.14 and Agent 0.13.4 versions and
bilingual notes, and restore the historical release documentation.

The merged product source, tests, dependencies, and approved release notes
are identical to d23af99, which passed 5127 tests. Post-merge release-note
checks, nine focused tests, full typecheck, and lint passed.

+# Desktop 0.13.13 Preparation
+
+Prepared on 2026-09-23 from `b16fc90`, relative to published Desktop `v0.13.12`.
+This is a Desktop-only release; Agent remains at published `0.13.3`.
+No LoongArch preview is requested.
+
+## Scope and isolation
+
+- `bf8ff7f` reduces repeated activity-history reads during streaming saves.
+- `b16fc90` restores compact supervision feedback controls and target names.
+- The candidate is prepared in a separate worktree. The user's uncommitted
+  supervision timeout tests in the original worktree are explicitly excluded.
+- Desktop and both root lockfile versions are `0.13.13`. Both feature matrices
+  and bilingual release notes were reviewed against this range.
+- Database schema and Agent/Runtime contracts are unchanged. The activity
+  comparison cache belongs to Desktop persistence; it does not modify the
+  deployed Agent, model bridge, or remote Runtime lifecycle.
+
+## Validation
+
+- Six focused files passed 192 tests: activity-history I/O, AssistantDatabase,
+  storage upgrades, sidebar interactions, SupervisionCard, and the Supervisor
+  Electron layout fixture.
+- Re-running `tests/supervisor-layout.electron.test.ts` with
+  `GOODBUDDY_SUPERVISOR_SIDEBAR=1` passed its additional sidebar scenario:
+  480, 300, and 200 pixel widths in both themes, no horizontal overflow,
+  compact 34px buttons, visible keyboard focus, and no raw target ID in body text.
+- `npm run release:notes:verify`, `npm run typecheck`, and `npm run lint` passed.
+- Ten consecutive activity saves performed one full-history scan. WAL and SQL
+  counters are not installed-application physical disk throughput measurements.
+- No real model requests, local full-suite rerun, production build, packaging,
+  or packaged-app probe were performed. UI validation uses production
+  components with isolated fixtures, not a real user database.
+
+The candidate must pass complete main-branch CI and its production build before
+an unused annotated `v0.13.13` tag is pushed to both remotes. Native six-platform
+packaging and public GitHub/OSS verification remain subsequent release steps.
