BDR-016: doc-syncer makes README AUTO+unconditional (no skip at
validation gate, only yes/edit) and DEPLOY.md prod-only with a
14-section VPS-deploy template. Mixed dev/prod DEPLOY.md flagged as
drift; dev quick-start lives only in README.
LRN-019: deployable-project doc split by audience — README = dev +
features, DEPLOY = ops + SRE. 14-section template mirrors real
VPS-deploy shape (topology, env, provisioning, two-layer firewall,
Docker tuning, persistence, backups, TLS, observability, hardening,
rollback, runbook). Drop sections that don't apply.
