feat(agents): W5 seo/geo 3-mode pipelines — collect sonnet / judge opus pin / template sonnet (BDR-077)

seo-analyzer + geo-analyzer gain MODE: collect|judge|template around the
dispatcher (mode-based, zero body-text moves — seo-data fetch-wiring
locks survive; opus pin kept = fail-safe direction, a forgotten override
over-tiers but never downgrades judgment). Run-scoped gitignored
signals handoff (.audit/*-signals-<RUNID>.md + COLLECTION COMPLETE
sentinel), judge fails closed on absent/mismatched/unsealed signals.
/seo rewired to 3 phases (domains parallel per phase) + DISPATCHER ERROR
CONTRACT (mute/ERROR judge never carried into templating; retry once,
escalate); /geo same single-domain; legacy no-MODE single-shot kept on
the opus pin for /harden narrow-scope + /onboard report-only. Dropped
/geo's 'ask and I relay' fiction (dispatched agents cannot ask).
In-wave smokes PASSED disk-verified: collect signals+sentinel; judge
ERROR-verdict on wrong RUNID; real judge = honest N/A + deterministic
engine + full scoring grammar; template = complete envelope + verbatim
sentinel + zero re-derivation. Census §18 (125 pass — one vacuous
line-wrapped lock caught by the census itself and fixed), make test
exit 0.
