castle deploy now manages the public zone's tunnel CNAMEs to match the current
set of public: true services — creating missing records and deleting removed
ones — instead of only printing manual 'cloudflared tunnel route dns' hints.
New core/generators/dns.py reconciles via the Cloudflare API (stdlib only). It
only ever touches records whose content is <tunnel_id>.cfargotunnel.com, so
hand-managed records in the same zone are never altered. deploy._write_tunnel_config
calls it in both branches (delete of the last public service cleans up its CNAME).
Without a token it's a no-op and the manual route-once hints are surfaced as before.
Token: ~/.castle/secrets/CLOUDFLARE_PUBLIC_DNS_TOKEN, a single DNS:Edit permission
scoped to the public zone (the 'Edit zone DNS' template) — confirmed sufficient:
that one permission resolves the zone by name and edits records, no separate
Zone:Read needed. Separate from CLOUDFLARE_API_TOKEN (ACME, internal zone).
castle doctor gains a read-only probe that WARNs when the token is absent (CNAMEs
stay manual) and FAILs when it can't reach the zone/records.
