Agent Skills: lisa-jira-validate-ticket

Validates a proposed JIRA ticket spec (or an existing ticket) against the organizational quality gates without writing anything. Returns a structured PASS/FAIL report per gate with concrete remediation. This is the single source of truth for what makes a valid ticket — both the write path (jira-write-ticket runs it pre-write) and the dry-run path (notion-to-tracker runs it during PRD intake) call this skill so the bar can never drift.
