docs(rfc): address Codex review — fence-aware format gate, exact corpus counts

Two findings from the pre-ready review, both verified:

- verify-rfc-format scanned raw lines, so an RFC quoting a Status line,
  a banned heading, or the grandfather comment inside a fenced example
  would false-positive. The content scans (duplicate Status, H2 headings,
  banned headings, grandfather, legacy marker) now ignore fenced blocks;
  the positional header-block checks stay raw. Verified: a fenced
  'Status: implemented' + '## Plan' + grandfather quote inside a walked
  RFC no longer trips the gate.

- The companion RFC's pre-format corpus counts were imprecise: 27
  distinct Status spellings (reasons collapsed), not 'some fifteen';
  nineteen implemented files carrying thirty proposal-era heading
  occurrences, not 'over twenty files'; three English files (plus one zh
  counterpart) with no status, not four.
