Follow HackerOne pagination and deduplicate overlapping reports. Reject
failed pages and invalid pagination links instead of returning a partial
candidate list.

Expose candidate retrieval and draft preparation without prompts or
publication. Reuse one candidate snapshot in the CLI and normalize dates
and release-line maps while preserving incomplete metadata for review.

Check out existing release branches without resetting them and reuse
remote-tracking branches when available. Reject unrelated staged files
before adding release changes to the index.

Expose local draft persistence with an explicit repository path and
exclusive file creation. Prepare data before changing branches and check
for an existing draft again after checkout.
