test(cypress): drop redundant uncaught:exception suppression in memory-router spec

[voidmatcha]

Description

Removes the per-spec Cypress.on('uncaught:exception', () => false) in apps/router-demo/router-host-2000/cypress/e2e/memory-router.cy.ts.

The global handler in cypress/support/e2e.ts already allow-lists the only errors this happy-path navigation flow can legitimately emit (the React-bridge Failed to construct 'HTMLElement' / Illegal constructor and the react-dom/client module-not-found cases) and returns true (fails the test) for everything else. The per-spec handler was strictly weaker: it swallowed every uncaught exception unconditionally, so a genuine regression in this flow would be silently hidden instead of failing. The sibling happy-path specs (remote1.cy.ts, remote2.cy.ts, remote3.cy.ts, host.cy.ts) already run the same federated-remote flow with no per-spec handler, relying on the global allow-list. This brings memory-router.cy.ts in line with them and restores real-error visibility.

The dedicated error specs (remote-render-error.cy.ts, remote-resource-error.cy.ts), which deliberately trigger errors, keep their handlers and are intentionally untouched.

Related Issue

No separate tracking issue. This is a small test-suite hardening with no behavior change to shipped packages. Happy to open an issue first if you prefer that for traceability.

Types of changes

• Docs change / refactoring / dependency upgrade
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

Checklist

• I have added tests to cover my changes.
• All new and existing tests passed (could not run the Cypress suite locally without the demo dev server; the change only removes an error-suppression handler).
• I have updated the documentation.

Found while reviewing the test suite with e2e-skills/e2e-reviewer.

Verified locally (cypress run, electron headless, Node 20):

• handler present: 4/4 passing
• handler removed (this PR): 4/4 passing

The flow throws no uncaught exception that the global handler in cypress/support/e2e.ts does not already allow-list, so the per-spec blanket () => false is redundant. Removing it keeps the suite green and restores real-error visibility.

As-Is: handler present

To-Be: handler removed

Bundle sizes are generated with rslib (Rspack). Package-root metrics preserve the historical report. Tracked subpath exports such as ./bundler are measured separately so ENV_TARGET-driven tree-shaking is visible. Bare imports are externalized to keep package-level sizes consistent, and assets are emitted as resources.
