V48 Gate 3 (specification-only): Keep V47 Gate 10 README verification surfaces

Restore required root README documentation of check:v47-gate10 and
v47-canon-promotion.yml so active-canon promotion readiness stays green
after the contributor README refurbish.

+## Promoted V47 verification (active pointer on `main`)
+
+Active canon on `main` is **V47**. Gate-quality CI still validates V47 promotion
+surfaces. Documented entrypoints:
+
+```bash
+# V47 Gate 10 promotion readiness (commercial website testnet launch close)
+pnpm run check:v47-gate10
+# or: node scripts/check-v47-gate10-promotion-readiness.mjs --promotion-mode --skip-branch-check
+
+# V47 canon promotion workflow (CI): .github/workflows/v47-canon-promotion.yml
+```
+
+Related: `generate:v47-promotion-readiness`, `.bitcode/v47-promotion-readiness-report.json`,
+`BITCODE_SPEC_V47_PROVEN.md`. Draft work after V47 uses **V48** (`BITCODE_SPEC_V48.md`).
