feat(social): screenshots for the 13 image tweets

[kipavy]

Adds social/media/<id>.png for #7, #11, #14, #15, #16, #20, #21, #33, #37, #39, #42, #46 and #47. Image tweets post without an approval issue.

• All are real captures of Voltius 0.49.1 at 2880×1620, on an isolated self-hosted sync server. Several show UI fixes that are open as PRs on voltius dev (#523, #525, #527, #530, #540, #545), applied to the capture build.
• fix(landing): drop the --no-quarantine Homebrew hint #15 is GitHub's own repo card for VoltiusApp/voltius (1200×600).
• feat(promo): tweet videos from real captures, rendered in one command #42: web-01 is a container on the capture machine, so the metrics are that machine's.
• feat(social): tweet videos #44 becomes a plain question ("What's the oldest box you still SSH into?"): no invented answer, no photo, no hold.
• feat(landing): scroll-driven device handoff and E2EE sync sections #38 loses its hold: the MCP audit_query tool answers it, checked against a real team-vault log. It still needs its video before it can post.

node social/post.mjs check: queue ok, 51 tweets. Dry run with SOCIAL_TODAY=2026-12-31: everything ready except #38 (needs video).
