Intermittent: drush en fails with 'no commands defined in the pm namespace' in contrib CI

[rfay]

Symptom

ddev drush en <module> -y fails with:

There are no commands defined in the "pm" namespace.
Failed to run drush en pathauto -y: exit status 1

The module is not listed in ddev drush pm:list --status=enabled, so the CI verify step also fails.

Observed in

• Job: Contrib pathauto D11 (plain, GH) and Contrib token issue fork (GH)
• Run: https://github.com/ddev/coder-ddev/actions/runs/25699102090/job/75454796037?pr=152
• Trigger: PR fix: clean working tree after issue branch checkout, fixes #151 #152 (unrelated to the failure — plain workspace tests don't exercise that PR's changes)

What succeeds before the failure

All prior steps pass:

• Clone ✓
• DDEV config ✓
• ddev-drupal-contrib addon ✓
• DDEV start ✓
• ddev poser ✓
• DDEV restart ✓
• ddev drush si minimal -y ✓ ← Drupal fully installed

Then immediately:

• ddev drush en <module> -y ✗ ← pm namespace not found

Notes

• The previous run against the same template code (commit b6c1e74, run 25684305046) passed cleanly for both pathauto and token
• The error occurs AFTER a successful drush si, which requires the same Drush bootstrap, making a permanent version mismatch unlikely
• Likely a timing or state issue after ddev restart / symlink-project, or a flaky interaction between the drush wrapper and the Drupal bootstrap in the web container
• Worth investigating whether adding a short ddev drush cr or checking drush bootstrap status before ddev drush en would stabilize this
