Add video analysis mode via Gemini CLI

[Abeansits]

Summary

• Adds video mode to query.sh — analyze local video files or YouTube URLs using Gemini's multimodal capabilities
• Accepts local files (@path syntax) or URLs (bare in prompt), auto-switches provider to Gemini
• Default prompt produces a structured Markdown table (Timestamp, Visual Narrative, Text & Graphics, Cinematography, Audio, Emotional Beat) plus symbolism/ad evaluation summary
• Updates /midflight skill with --video <file-or-url> flag support
• Sandboxes local files via temp staging dir (copy, not symlink) to avoid exposing parent directories
• Hard-fails on stat failure instead of silently bypassing the 20MB size guard

Use case

Paul generates video ads for the Judah app. The Slack conductor needs to "watch" these videos and provide scene breakdowns, quality feedback, and content verification — without Sebastian being involved.

Usage

# Direct — local file with default scene breakdown
query.sh ./ad-v3.mp4 video

# Direct — YouTube URL
query.sh "https://youtube.com/watch?v=abc" video

# Direct — custom prompt
query.sh ./ad-v3.mp4 video "Does this match the storyboard?"

# Via skill
/midflight --video ./ad-v3.mp4 Does this match our brand guidelines?

Test plan

• Local file: scene breakdown with default prompt (13MB mp4)
• YouTube URL: default prompt produces full table output
• Custom prompt: responds to specific question about the video
• Backward compat: consult mode routes to Codex as before
• Error paths: missing file, empty args, file-not-found
• Staging dir cleaned up on exit
• Codex code review via midflight — addressed security feedback
