fix(preview): preserve direct localhost navigation

[Chrrxs]

What Changed

• Treat preview address-bar submissions as direct URL targets by using the existing explicit { kind: "url" } navigation intent.
• Normalize schemeless direct targets (localhost:5173 to HTTP and public hosts to HTTPS) without consulting the environment connection or remapping loopback hosts.
• Keep empty-state server cards on discovered-server routing, including WSL environment-host remapping.
• Add regression coverage for explicit localhost URLs, schemeless direct targets, and empty-state server-card remapping.

Why

Address-bar submissions incorrectly reused the resolver intended for discovered servers. In WSL environments, that resolver replaced loopback hosts with the environment IP, so entering https://localhost:8000/dashboard?mode=test#top navigated to https://172.25.85.75:8000/dashboard?mode=test#top instead.

Using the existing direct-URL intent fixes that boundary without adding a new abstraction or changing server-discovery behavior. Direct targets still use the shared URL normalizer, preserving the prior scheme defaults for schemeless input. Fixes #3938.

UI Changes

No visual UI, animation, motion, timing, or interaction-design changes. The deterministic navigation result changes as follows:

	Address-bar result
Before	The entered loopback host could be replaced with the WSL environment IP.
After	The entered protocol, loopback host, port, path, query, and fragment are preserved.

Screenshots and video are therefore not applicable.

Validation

• vp test run --passWithNoTests --project unit from apps/web — 1,283 tests passed
• vp run typecheck from apps/web
• vp check from the repository root
• vp run typecheck from the repository root — all 15 workspace tasks passed

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes (not applicable; no visual UI change)
• I included a video for animation/interaction changes (not applicable; no animation or interaction-design change)

Note

Low Risk
Narrow preview navigation routing change with regression tests; no auth, data, or broad architectural impact.

Overview
Fixes preview address-bar navigation in remote environments (e.g. WSL) where typed loopback URLs were incorrectly rewritten to the environment host IP.

Address bar submissions now go through resolveBrowserNavigationTarget with { kind: "url" }, which applies normalizePreviewUrl for schemeless input but does not remap loopback hosts via the environment connection. Empty-state discovered servers still use resolveDiscoveredServerUrl via handleOpenServerUrl, so localhost dev servers continue to map onto the WSL/private-network host when picked from the server list.

Regression tests cover direct localhost preservation, schemeless direct URLs, empty-state remapping, and resolver unit behavior.

Note

Fix direct localhost URL navigation in preview chrome row

• URL submission via the chrome row now calls normalizePreviewUrl instead of resolveDiscoveredServerUrl, preserving direct localhost URLs rather than remapping them to the environment host.
• URLs opened from the empty state still go through resolveDiscoveredServerUrl via a new handleOpenServerUrl handler in PreviewView.tsx.
• A shared navigateToResolvedUrl callback centralizes the logic for driving previewBridge.navigate and calling rememberPreviewUrl.
