SPEC v0.3: orchestrator resolutions of the plans' open points

Records D-004 and D-015 to D-025: shells and ownership, server seams
(router middleware, rate_limit layer, tasks::start, AuditWriter and PushQueue
traits, next_occurrence_date in kvitt-domain, M3 owns recurring generation,
M4 lands after M3), OpenAPI parsed-value equality, feature convention and
strings, empty fake scenario and resolveRange exception, shared ledger rows and
editor fields in :core:design, no bundled font, pruning at 04:00, development
infrastructure as M2c-dev built it, M2c-pi allowances, release keystore,
production import procedure. Plans and prompts close their open points;
HANDOFF rewritten to the real state; CLAUDE.md: implementation agents never
edit SPEC.md or docs/decisions.md.
