v1.2.4 — native ranking tab, themed panel, dark-friendly selects

Re-draws the router's own model table inside the DSH panel, and brings the panel onto the DSH design tokens.

Ranking tab

• Reads the router database read-only and reuses the vendored getModelGroups() / getRoutingScores(), so the stability / speed / intelligence axes and the 0..1 score are the same numbers the :3001 console shows. Nothing is recomputed.
• Sortable columns, search, and vision / tools / context-size filters.
• Per-row enable switches, plus tick-untick bulk actions over the currently shown set.
• A missing or locked database degrades to "scores unavailable" - the model list keeps working.

Colour and surfaces

• Accents come from DSW alias tokens and color-mix() instead of fixed hex values, so the panel follows light and dark themes.
• Flat list surfaces no longer stack bg-layer-3/bg-layer-4 on top of the card's raised surface. Cards are bg-layer-1 with a hairline border; rows are transparent with an inset border.

Native selects

• A native <select> popup is drawn from color-scheme, which the host never set - so on a dark theme the list opened white with a blue highlight. The panel now measures the active theme and applies color-scheme to its root, with a MutationObserver so a theme flip is picked up without a reload.

Console link

• "Open the full console" from the ranking tab and the status card, for provider keys, usage and routing policy.

Install

The tarball below is self-contained: vendor/node_modules (the router's runtime closure) ships inside it, because the repository does not commit node_modules. Installing straight from the git tree will produce a router that cannot start.
