Nx Cloud is proposing a fix for your failed CI:

These changes update the test expectations to align with the new pagination response format introduced in this PR. The nx_project_details tool now always includes a "Project Details: " prefix in the response, even for filtered results, to support the chunking and pagination mechanism. The tests were updated to use .toContain() assertions instead of exact matches to accommodate this new format.

We verified this fix by re-running nx-mcp-e2e:e2e-ci--src/nx-project-details-filter.test.ts.
