What changed

Advances the embedded openkara-models catalog snapshot from generation 12 (2026-08-07-002) to generation 13 (2026-08-12-001, upstream release infra-2026-08-12-001):

• src-tauri/catalog/release-manifest.json — new upstream release manifest with the OpenKara-side model annotations (capability_limit / evaluation_fixture / known_user_effect) re-applied unchanged.
• src-tauri/catalog/stable-pointer.json — release_id / generation / digest / size / URL advanced to the new embedded manifest.

Generation 13 rebuilds all six reduced runtimes; the two Windows runtimes are now linked with the static MSVC CRT (/MT) (CMAKE_MSVC_RUNTIME_LIBRARY=MultiThreaded plus ONNX_USE_MSVC_STATIC_RUNTIME / protobuf_MSVC_STATIC_RUNTIME / ABSL_MSVC_STATIC_RUNTIME), so onnxruntime.dll no longer imports VCRUNTIME140* / MSVCP140* and loads on clean Windows installs without the VC++ Redistributable. Refs #363, #284; upstream thedavidweng/openkara-models#90 (build flags) and #91 (generation 13 catalog). Models and the four non-Windows runtimes are functionally unchanged: same upstream v1.27.1, unchanged build flags, fresh archives/digests from upstream publish run 31670494161.

The CPU Windows runtime keeps catalog target_triple x86_64-pc-windows-msvc (generation-12 convention) so resolve_runtime still disambiguates the two Windows runtimes by execution provider.

This PR only advances the snapshot. Removing the #361 app-local CRT mitigation is the follow-up step on #363's checklist once this generation is live on main.

Verification

• pnpm format:write — no further diff (manifest bytes stable; stable-pointer.json digest matches embedded file: sha256 de0248138f7d1de0eaa50e5eaa6afd52c961066c95c69126e827c3fd29b5182d, 113482 bytes)
• pnpm lint — PASS
• pnpm test — PASS (2236 tests / 196 files, via pre-push hook with coverage + patch-coverage)
• cargo test --lib separator::catalog — PASS (27 tests, includes embedded snapshot/pointer self-consistency)
• node scripts/prepare-onnx-runtime.mjs fresh-staged from the new release (download + size + archive digest + per-file digests) for 3 targets:
  • --target x86_64-pc-windows-msvc --provider directml — PASS
  • --target x86_64-pc-windows-msvc --provider cpu — PASS
  • host aarch64-apple-darwin (default) — PASS
• Upstream: PE import tables of both Windows onnxruntime.dll variants verified clean of VCRUNTIME140* / MSVCP140* (remaining api-ms-win-crt-* imports are the UCRT, which ships with Windows 10+)

Gaps

• Windows installed-app behavior is only provable in Windows CI, and src-tauri/catalog/** is not in the Branch Windows installed-app gate's pull_request path filter — so I dispatched it manually on this branch (suite=full): github.com/thedavidweng/…/31674410572. The #361 app-local CRT DLLs remain bundled by this PR, so that workflow's CRT assertions still hold here.
• pnpm tauri build not run locally (covered by CI).
• The three remaining runtime archives (linux x64/arm64, macOS x64) were not re-downloaded locally; their digests were verified by the upstream publish pipeline's verify step.

Residual risk

Low. Models are byte-identical to generation 12; non-Windows runtimes rebuilt with unchanged flags from the same pinned source; existing installs pick up generation 13 via catalog auto-discovery without an app release.
