README + site + binary: surface 22-of-26 VM-verified count

Updates the visible 'how trustworthy is this' signal across all three
touchpoints after the verifier sweep landed 22 modules confirmed in
real Linux VMs:

README.md
  - Badge: '28 verified + 3 ported' → '22 VM-verified / 26'.
  - Headline tagline: emphasizes the 22-of-26 empirical confirmation.
  - 'Corpus at a glance' restructured: tier counts unchanged, but the
    stale '3 ported-but-unverified' subsection is replaced by a new
    'Empirical verification' table breaking the 22 records down by
    distro/kernel.
  - 'Status' section refreshed for v0.6.0 reality: 88 tests + 22
    verifications + mainline kernel fetch + --explain + KEV/CWE/ATT&CK
    metadata + 119 detection rules. The four still-unverified entries
    (vmwgfx, dirty_cow, dirtydecrypt, fragnesia) are listed with their
    blocking reasons.

docs/index.html
  - Hero stats row gets a new '22 ✓ VM-verified' chip (emerald-styled
    via new .stat-vfy CSS class), keeping modules/KEV/rules siblings.
  - Hero tagline calls out '22 of 26 CVEs empirically verified'.
  - Meta description + og:description updated.
  - Bento card 'Verifier ready' rewritten as '22 modules empirically
    verified' with concrete distro/kernel breakdown; styled with new
    .bento-vfy class for emerald accent (matches the stat chip).
  - Timeline 'shipped' column adds the verifier wins; 'in flight'
    swapped to current open items (drift fixes, packagekit provisioner,
    custom <=4.4 box for dirty_cow).

docs/og.svg + docs/og.png
  - 4-chip stats row instead of 3: 31 modules · 22 ✓ VM-verified · 10
    ★ in CISA KEV · 119 detection rules. Tagline now '22 of 26 CVEs
    verified in real Linux VMs.' Re-rendered to PNG via rsvg-convert.

skeletonkey.c (binary)
  - --list footer now prints '31 modules registered · 10 in CISA KEV
    (★) · 22 empirically verified in real VMs (✓)'. Counts computed
    from the registry + cve_metadata + verifications tables at runtime
    (so it stays accurate as more verifications land — the JSONL
    refresh propagates automatically).

No code logic changed; only surfacing.
