pi-ts-aperture v0.13.0

37d6620: Add per-provider keepGatewayModelsOnly in proxy.upstreamProviders (default false). When enabled on a proxied provider, its registered models are filtered down to the ones the Aperture gateway actually serves (same /api/providers + /v1/models cross-reference as shouldCheckGatewayModels), instead of rerouting every local model and failing at request time. The drop is reported once per sync with per-provider counts, providers with no models left are skipped like providers with no local models, and the catalog fetch fails open. Toggling the flag off restores the full model list on the next resync. Also editable per provider from the Proxy tab in /aperture:settings.

38390a5: Bump @aliou/pi-utils-settings to ^0.20.0 and adopt the fixed-height settings layout: /aperture:settings renders at a fixed content height (SETTINGS_CONTENT_HEIGHT in settings/shared.ts), detail editors bottom-anchor their descriptions inside the same budget, and submenus forward hideHint / expose getShortcuts() so the panel’s single controls line always shows the open submenu’s shortcuts. Onboarding wizards render unchanged.
