[deep-report] [quick-win] Fix asymmetric `expires` default between create-issue and create-discussion

[github-actions]

Problem

Schema Consistency Check (#36193, finding #10) found that the expires default is asymmetric across sibling safe-output configs in pkg/parser/schemas/main_workflow_schema.json:

• create-discussion.expires sets default: 7
• create-issue.expires has no default (null)

This is surprising and undocumented divergence — a workflow author reasonably expects the two to behave the same.

Suggested fix

Decide the intended default and apply it consistently:

• If issues should also auto-expire → add default: 7 to create-issue.expires.
• If the divergence is intentional → document why in the schema description so it isn't flagged as a bug each audit cycle.

Success criteria

• expires defaults are consistent across create-issue / create-discussion, or the difference is explicitly documented.

Effort

~20 min. Suggested agent: schema maintenance agent.
