docs(readme): round-12 Node Foyer showcase facts

[HomenShum]

Summary

Updates the README's "Node Foyer" showcase section (previously titled "FOYER-V3 R1", stale
since PR #10) to reflect round 12 (PR #12, commits abb5c83 and e3b7e4d) instead of
round-10/11 facts.

• FYwall beat 02 now names NodeSlide's two-layer "matches backend" apparatus, not NodeVoice
  (whose own pill reads "1 layer" on the same frame — a caption that was false of its own
  frame). Beat 00 now says "every half hour" (LEDGER_SWEEP_MINUTES = 30), not "every few
  minutes". Verified against walkthrough.foyer.specs.mjs and commit abb5c83's message.
• Judge verdicts corrected against node-foyer's sealed manifest
  (D:/VSCode Projects/node-foyer/public/media/walkthroughs.json, studioCommit
e3b7e4d, read-only): FYwall publish, 0 P0 / 1 P1 / 1 P2, comprehension passed,
  published: true. FYphone publish, 0 P0 / 0 P1 / 1 P2, but comprehension blocked
  (wouldMomUnderstand: false) on the worse of the 2 kept judge runs, so published: false
  — captured but not on the wall. FYagent rework, 2 P0 / 2 P1, comprehension blocked on
  non_expert_sense, published: false. The old copy quoted round-10/11 numbers
  (fix-then-publish 20/22, fix-then-publish 22/22, rework "13/8/6 out of 22") that no
  longer match any judge record for the current captures.
• Removed stale round-10/11 language: NodeVoice/NodeProof card pairing (no longer part of the
  FYwall spec — current cards are __fixture_dead, NodeSlide, NodeRoom, node-foyer per
  walkthrough.foyer.specs.mjs), "every few minutes", and the old out-of-22 scoring format.
• Added a short "regenerate" line citing the repo's own scripts: npm run capture:foyer
  (package.json), node run-remotion.mjs render src/foyer-index.js WT-FYwall out/foyer-FYwall.mp4 (composition IDs from src/FoyerRoot.jsx), and npm run judge.

Facts and evidence

Claim	Evidence
FYwall beat 02 caption/assert targets NodeSlide, checks "matches backend"	walkthrough.foyer.specs.mjs (FYwall steps), public/wt/FYwall/capture.json frame 02
Beat 00 says "every half hour"	walkthrough.foyer.specs.mjs FYwall step 1 cap; commit abb5c83 message
FYwall: publish, 0 P0/1 P1/1 P2, comprehension passed, published	node-foyer/public/media/walkthroughs.json → captures[0].judge, captures[0].published
FYphone: publish, 0/0/1, comprehension blocked, not published	same manifest → captures[1].judge, captures[1].published
FYagent: rework, 2 P0/2 P1, comprehension blocked (non_expert_sense), not published	same manifest → captures[2].judge, captures[2].published
Judge runs twice, worse run kept	commit abb5c83 message ("2 runs kept-worse"); manifest judge.runs: 2 on all three
GIF assets exist at the paths the <img> tags reference	assets/feature-foyer-FYwall.gif, -FYphone.gif, -FYagent.gif
node check.mjs unaffected (doesn't scan README.md for citations)	check.mjs only scans .tours/*.tour and docs/START_HERE.md; confirmed no README.md line-citations exist in either

Verification

• node check.mjs → [check] parsed 60/60 JavaScript files; 36/36 tour steps and 34/34 prose citations name a line that matches, exit 0.
• git diff --stat → only README.md changed.

Test plan

• node check.mjs exits 0
• Only README.md touched
• Not merged
