feat(web): remove Browser from the surface picker

[Dillpickleschmidt]

Browser previews are desktop-only, so on web the "Open a surface" grid always rendered a permanently disabled Browser card.

Dropped it from the grid, along with the now-unused onAddBrowser and browserAvailable props on RightPanelEmptyState.

Scope is the card alone. Browser stays in the "+" menu, keeps its six preview.* keybindings, and existing browser surfaces are unaffected — Globe2, SURFACE_DISABLED_REASONS.browser, and both props remain live on the parent, which the menu still uses. Left a comment at the component so its absence from the grid does not read as an oversight.

Deliberately not the general "hide unavailable cards" refactor: showing a disabled card with a tooltip is intentional elsewhere, since it tells the user the feature exists and why it is unavailable.

Note for review

AGENTS.md asks for before/after images on UI changes and I have not attached any — it needs a browser session, which I have not been given the go-ahead for. The visible change is one card removed from a grid-cols-2, taking it from four cards to three, so the grid is briefly ragged until the 3D surfaces land and restore a 2×2. Happy to attach screenshots on request.

Typecheck clean, vp lint clean, rightPanelStore.test.ts 27 passed. No test covers the picker's card list directly.

Closes #3.

Note

Remove Browser from the web surface picker in the right panel

Removes the Browser action from RightPanelEmptyState in RightPanelTabs.tsx, since Browser surfaces are desktop-only. The onAddBrowser and browserAvailable props are deleted and a comment is added to document the intentional omission.

Before / after

Captured from a real client per AGENTS.md, against an isolated dev environment seeded from real data.

Before — Browser present but permanently disabled on web, four cards in a clean 2×2:

After — Browser gone, three cards:

The greyed-out Browser card in the first image is exactly the thing this removed: on web it could never be clicked, only hovered for a tooltip explaining it is desktop-only.

Also visible is the consequence noted at merge time — the grid is grid-cols-2, so dropping to three cards leaves Diff orphaned on its own row. Adding 3D Watch Agent restores a clean 2×2; adding 3D Diff as well makes it five and ragged again. That belongs with whatever lands the new cards, not here.

Images live on the assets/pr-14-screenshots branch rather than main, to keep binaries out of the tree.
