Pull request overview
This PR expands and adjusts the frontend test suite (largely MCP hook tests) based on recovered agent output, aiming to increase coverage and reduce flakiness from JSDOM/runtime quirks and module-level caches.
Changes:
- Adds extensive unit tests for
kagent_crdshooks and broadens coverage for several MCP hooks (Crossplane, clusters, workloads, security). - Tweaks existing tests to better reflect runtime behavior (e.g., demo mode precedence, JSDOM event-target limitations).
- Updates some tests to avoid cache-related intermittency (though a couple changes currently weaken assertions too far).

This test now hand-builds a contentEditable div, but the existing createContentEditable() helper at the top of the file is no longer used. That will trigger @typescript-eslint/no-unused-vars warnings; either reuse the helper (and patch isContentEditable inside it) or delete the helper.

The test name says it verifies behavior when no cluster is specified, but it actually calls useBuildpackImages('url-check-cluster') (cluster provided) and then conditionally asserts only if fetch was called. That makes the test both misleading and able to pass without asserting anything. Suggest either (1) render with useBuildpackImages() and assert the requested URL does not include cluster=, while ensuring module-level cache is reset so a fetch occurs, or (2) rename the test and unconditionally assert fetch was called with the expected cluster param (though that’s already covered by the prior test).

This assertion is intentionally non-deterministic because useAllPods only sets error when !silent && !podsCache (podsCache is module-level and may be left populated by earlier tests, even with a different cacheKey). Rather than weakening the expectation to just Array.isArray(...), reset the module-level workloads caches in test setup (e.g., invoke the callback passed to registerCacheReset or reload the module with vi.resetModules) and keep a deterministic assertion for the error behavior.

Similar to the useAllPods test above, this test became cache-order dependent (deploymentIssuesCache is module-level and can be populated by earlier tests), so it no longer asserts the intended error branch. Please reset module-level caches between tests (e.g., via the registerCacheReset callback / module reload) and assert the expected error value for the no-cache failure case.
