`issue-assessment` — triage a gflow-cli issue honestly

Read-only conductor. Verify the reporter's claim against the code, tests, docs, KNOWN_ISSUES.md, and auto-memory; classify it; judge whether it can be verified end-to-end in the current environment; and draft a reply. The output is a standard artifact a human or the issue-resolve skill can act on.

Core principle: never assert more than the evidence supports. A claim is CONFIRMED only with line-level code evidence or a reproduction; a fix is "verified" only after running it on the affected surface. Honest "can't verify here" beats a false green check — a bounced fix costs more trust than an accurate "not yet."
