shipshitdev Required sections:
- Executive Summary
- Problem Statement
- Goals
- Functional Requirements
- Acceptance Criteria
- Verification Plan
When the quality gate is ENABLED (blocking):
- Missing any required section → pipeline fails immediately with an actionable message listing the missing sections.
- The user must update the issue body and re-trigger the pipeline.
When the quality gate is DISABLED (default, warning-only):
- Missing sections → a warning is logged to the terminal lifecycle stream.
- Planning proceeds. The planner should still note gaps in its output.
Section matching is case-insensitive against ## and ### headings. Exact heading text must appear (e.g. "## Executive Summary" or "### Goals"). Headings nested inside code fences are ignored by convention (they are examples, not structure).
