The v0.0.4 publisher created its draft successfully, then failed with Draft release was not retained. because GitHub's release list did not yet contain it. Publication now uses the creation response immediately. Subsequent lookups fetch release details by ID, falling back to GitHub's pending-tag lookup when a draft is missing from the list, so retries reuse the existing draft and its files. API errors still stop publication.

Regression tests cover stale lists during creation and recovery, and failed direct lookups. Add the standard Covered::Sus integration for reproducible coverage checks.

Validation:

• COVERAGE=PartialSummary bundle exec sus-parallel: 44 tests, 126 assertions; every changed publisher line covered.
• RuboCop: 24 files, no offenses. Documentation coverage: 21/21 public definitions.
• Hosted integration test reproduced the stale list, then exercised the actual fixed publisher: four files retained, the same draft reused on immediate retry, and identical bytes restored. Temporary drafts were removed.

The original v0.0.4 files have been verified and restored to its existing draft. The original publishing run can resume without rebuilding or preparing another version.
