/**
 * Regression test for the strict server-side `.temp/` path exclusion in
 * `listRegisteredProjects` (project-context.ts).
 *
 * The pattern `/(^|\/)\.temp(\/|$)/` must:
 *   - match `.temp` anywhere in a path that is bordered by `/` or string boundaries
 *   - NOT match paths that merely contain "temp" or ".tempfoo"
 *
 * This rule is non-negotiable: `.temp/` is reserved for ephemeral fixture/scratch
 * state and MUST never appear in the project switcher or any client-side list.
