Route shared session navigation by Factory access

[warp-agent-staging]

Description

Routes the simplified WASM shared-session and conversation header back into Factory for Factory-enabled users while retaining legacy Oz navigation for other users. The authoritative Factory access probe controls both the Warp logo destination and the adjacent product action; loading and request failures remain on the legacy Oz fallback.

• The linked issue is labeled ready-to-spec or ready-to-implement.
• Where appropriate, screenshots or a short video of the implementation are included below (especially for user-visible or UI changes).

Testing

• cargo nextest run -p warp -E 'test(factory_access_request) | test(factory_access_updates_workspace_navigation_asynchronously) | test(denied_factory_access_keeps_legacy_destination_and_refreshes_button) | test(failed_factory_access_preserves_loading_fallback) | test(simplified_wasm_navigation)' (7 passed)

• ./script/format

• cargo clippy --workspace --exclude warp_completer --all-targets --tests -- -D warnings

• cargo clippy -p warp --all-targets --tests -- -D warnings

• cargo clippy -p warp_completer --all-targets --tests -- -D warnings

• ./script/wasm/bundle --check-only --channel dev

• Built the local-channel browser bundle and verified Factory action, Warp-logo, denied-access fallback, and failed-probe fallback navigation

• Independently decoded the four new H.264 MP4 recordings: 69, 69, 69, and 20 frames (1.33–4.60 seconds)

• ./script/presubmit previously passed formatting, clippy, clang-format, Factory-file validation, and WGSL formatting; the full workspace test phase could not finish after the sandbox ran out of disk space while linking TUI test binaries.

• I have manually tested my changes locally with the browser-built WASM app

Computer-use video recordings (9)

Warp shared-session header load attempt: Navigating to the Warp shared-session URL, waiting for the WASM bundle to initialize, and observing that the header never renders due to a fatal 'env' module resolution error, then attempting to locate/click the product navigation action next to Open in Warp.

Loading Warp shared-session page and testing header navigation: Recording a fresh browser tab loading http://localhost:8080/session/00000000-0000-4000-8000-000000000001, observing the header once rendered, and clicking the secondary product navigation control next to Open in Warp.

Skip login and click secondary product action in session header: Recording the flow of completing the skip-login path on the Warp session welcome gate, observing the resulting simplified header with the Warp logo and "View in Oz"/"Open in Warp" actions, then clicking "View in Oz" and showing the resulting destination.

Clicking View Factory beside Open in Warp on the Warp session page: Shows the authenticated representative session page header with Warp logo, View Factory, and Open in Warp actions, then clicking View Factory to navigate to the Factory destination.

Shared-session header and Warp logo navigation: Shows the authenticated shared-session header with View Factory and Open in Warp buttons, then clicks the Warp logo at top-left and shows the resulting destination.

Clicking View Factory button in Warp shared-session header: Shows the fully loaded shared-session header, clicking the 'View Factory' text button beside the 'Open in Warp' desktop control, and the resulting navigation to the Factory destination page.

Clicking far-left Warp logo on shared-session header: Shows the stable Factory-enabled shared-session header at localhost:8080/session/00000000-0000-4000-8000-000000000001, clicking the small Warp logo at the far left of the header, and the resulting navigation to the destination page.

Denied Factory access falls back to legacy Oz: Shows the authoritative allowed:false response, the resulting View in Oz action beside Open in Warp, and navigation to the legacy /runs destination.

Warp shared-session fallback navigation to legacy Oz destination: Shows the stable failed-probe shared-session header, clicking the "View in Oz" fallback text button beside "Open in Warp", browser navigation, and the resulting legacy destination page with heading and requested path.
