docs(map): capability-map evidence audit — verify every status claim against source

Opened every citation in 00-capability-map.md and judged each of the 55 rows
against the specific scenario (not topic adjacency). 23 confirmed (incl. 5
MISSING proven-absent by code sweep), 26 citation-corrected, 6 demoted; no
upgrades. Status: 32 PROVEN-LIVE / 15 IMPLEMENTED / 3 PARTIAL / 5 MISSING
(was 38 PROVEN-LIVE).

Demotions PROVEN-LIVE->IMPLEMENTED: B6 (post-deploy config — T-PAGE-ALL is
render-only), E7 (FileBrowser access — no browse/download proof), F1 (health
email — cited P3-DELIVERY is the enlarge-block trigger), F4 (metrics — cited
legs are H1/H2 harness artifacts), F6 (operator alerting — no corpus doc),
G6 (offsite fill/staleness/freeze — no live-fired leg, freeze inconclusive).

Key corrections: D6 cited CAMPAIGN-3 F10/F11/F12 which are the CRITICAL
failures — fixes shipped agent v0.85 and were re-validated live in CAMPAIGN-4
/6A; C6 cited offbox-restic doc for a PBS-restore claim -> CAMPAIGN-2 T-P9;
C1/C5/B5 cited defect-discovery docs instead of the fix-validation legs.

Closed ROADMAP R-20: operator-key pinning is fully automatic in day-0
(felhom-host-install.sh step_agent_config, L2044/2146-2156/2332-2337).
Header draft caveat swapped for the verified stamp. Full per-row verdict
table in REPORT.md.
