First operator-facing README. Covers quick start (build, configure,
first-user login), the multi-drive batch workflow with concrete time
estimates, the four drive-lock states with their confirm tokens,
notable settings, daily report / notifications, ops cookbook (logs,
user CLI, backups, /health probe, DB reset), and an honest "known
gaps" list.
Cross-references CLAUDE.md (architecture + rationale) and SPEC.md
(per-version feature reference) for deeper docs.
