What does this PR do?

Avoid reading Solid Query's suspending data resource while a child path query is pending. This preserves the requested-directory fallback so the home session list can render before /path resolves.

The unit mock now throws if pending path data is read, covering the regression introduced when child directory queries moved from useQueries() to useQuery().

How did you verify your code works?

• Reproduced e2e/regression/session-list-path-loading.spec.ts failing on current dev
• Ran bunx playwright test --project=chromium --workers=1 from packages/app: 5 passed
• Ran bun run test:unit from packages/app: 339 passed
• Ran bun typecheck from packages/app
• Push hook repository typecheck passed

Pull request overview

This PR fixes a regression in the app’s global sync child store by preventing Solid Query’s suspending data resource from being accessed while the child path query is still loading, preserving the “requested directory” fallback so the session list can render before /path resolves.

Changes:

• Update child-store path getter to return a fallback value while pathQuery.isLoading is true (avoids reading suspending data).
• Strengthen the unit test mock to throw if pending path query data is read, ensuring the regression is covered.
