issue-resolve — drive an assessed issue to a draft PR

Takes a verdict from issue-assessment and produces a reviewable fix. The terminal state is a draft PR a human promotes — never an autonomous merge.

Core principle: the agent's job is to get the problem review-ready, not to declare victory. A fix is "verified" only after it runs green on the affected surface; when that surface can't be reached here (headed Flow browser, macOS-only, credits), say so in the PR and stop. (Memory: done-means-e2e-verified, pr-must-verify-on-affected-surface.)

The Bug Lane — canonical here, cited everywhere

This is the chain a bug travels in gflow-cli. It is written out once, in this file. AGENTS.md, skills/spike, skills/scenario and docs/E2E_TESTING.md all point here — none of them restate it, because a duplicated checklist drifts.
