Agent Skills: pr-fix-angles

Parallel disjoint-lane fix campaign — the execution companion to pr-audit-angles. Takes a set of verified findings and fixes ALL of them across multiple subagents that edit IN PARALLEL without merge conflicts, by partitioning the findings into lanes of exclusive file ownership. A lane whose findings share a file runs as sequential stages; independent lanes run concurrently. Each agent returns a structured completed/deferred/tests report; the orchestrator owns the single final lint→build→test gate and never commits without you. Use after an audit ("fix all the findings", "patch everything blocker→minor", "make it merge-ready"), or for any many-file coordinated remediation. Triggers on "fix all findings", "fix campaign", "remediate the PR".
