v0.3.1 — v2 enforcement + desktop video fix

What's new

v2 Schema Enforcement

• report command now rejects non-v2 run.json — requires mode, steps[].outcome, and steps[].do
• Clear error message tells agents to run flow-walker verify first
• No more silent "undefined" in reports from hand-crafted data

Desktop Video Recording Fix

• Replaced screencapture -v (broken by TCC) with ffmpeg via Terminal.app
• Terminal.app has Screen Recording permission — bypasses TCC entirely
• Tested on macOS Tahoe M4: 1920x1080, 10fps, h264, ~150KB for 20s

Pipeline Documentation

• record schema documents the full 6-step mandatory pipeline
• verify schema says "REQUIRED after record finish"
• report schema says "Requires verify — rejects v1/non-v2 data"

Stats

• 321 tests, typecheck clean
• Synced from beastoin/autoloop Phase 10+11
