Full PHP test loop misses cleanup classifier autoload

[chubes4]

Problem

The repository-wide PHP test loop fails after the workspace tests because tests/worktree-active-no-signal-scope.php loads WorkspaceWorktreeInventoryCleanup.php without loading WorktreeCleanupCandidateClassifier.

Reproduction

for test in tests/*.php; do php "$test" || exit 1; done

Observed on current origin/main (358cbb4) and independently during the Homeboy promotion gates for #951:

Class "DataMachineCode\Workspace\WorktreeCleanupCandidateClassifier" not found
inc/Workspace/WorkspaceWorktreeInventoryCleanup.php:84

Expected

Every standalone PHP test loads its direct runtime dependencies or a shared test bootstrap so the repository-wide loop reaches all tests.

Relationship

This is unrelated to #951. Its targeted gate, php tests/workspace-command-startup-bounds.php, passes before and after rebasing onto current main.
