Add template: peach.build.hosting

[grega91]

Description

New template for Peach (peach.build), a 3D web-experience builder. A single static
CNAME points the customer's www host at our Cloudflare-for-SaaS endpoint
(domains.peach.build); TLS certificates are issued automatically on our side.
The service is live; discovery and the sync apply flow are implemented per spec.

Type of change

• New template
• Bug fix (non-breaking change which fixes an issue in the template)
• New feature (non-breaking change which adds functionality to the template)
• Breaking change (fix or feature that would cause existing template behavior to be not backward compatible)

How Has This Been Tested?

• Template functionality checked using Online Editor
• Template file name follows the pattern <providerId>.<serviceId>.json
• resource URL provided with logoUrl is actually served by a webserver

Checklist of common problems

• syncPubKeyDomain is set — justification for omission: the template contains no
  variables and a single static CNAME record pointing at the provider's fixed customer
  endpoint. Applying it is byte-identical to creating the same public record manually, it
  grants no access on the Peach side (attaching a domain to content additionally requires
  authenticated ownership of that content in our platform, verified independently of DNS),
  and no user data flows through the apply URL. We're happy to add signed requests in a
  follow-up version if preferred.
• warnPhishing is not set alongside syncPubKeyDomain
• syncRedirectDomain is set whenever the template uses redirect_uri in the synchronous flow (N/A — redirect_uri not used)
• no TXT record contains SPF content (no TXT records in this template)
• txtConflictMatchingMode is set on every TXT record that must be unique (N/A — no TXT records)
• no variable is used as a bare full record value (N/A — no variables)
• no bare variable is used as the full host label (N/A — no variables)
• no variable is used in the host field to create a subdomain (N/A — no variables)
• %host% does not appear explicitly in any host attribute
• essential is set to OnApply on records the end user may need to modify or remove without breaking the template (N/A — the single CNAME is the service; removing it is intentional disconnection)

Re-consider using syncPubKeyDomain.
Yes, the template has no variables but still some providers require it by policy and the templates need to be updated.
