[dependabot]

Bumps github.com/caddy-dns/selectel from 1.1.0 to 1.2.0.

Release notes

Sourced from github.com/caddy-dns/selectel's releases.

v1.2.0

What's changed

Requires github.com/libdns/selectel v1.2.0 (released simultaneously).

New features

• enable_debug_logging now accepts an optional value: bare flag = true, or {env.VAR} / true/false/1/0 for env-controlled toggle
• Provider logs flow through Caddy's configured log routing (zap adapter injected via ctx.Logger()) instead of writing directly to stderr

Improvements

• Single caddy.NewReplacer() call in Provision (was one per field)
• Strict subdirective validation with named error messages
• Updated README with required/optional directive tables and debug logging guide

Dependency

• Upgraded to github.com/libdns/selectel v1.2.0 which brings security fixes, correct libdns semantics, Selectel API v2 contract compliance, per-zone parallelism, token refresh, and 37 new unit tests — see the libdns/selectel v1.2.0 release notes for the full list.

Commits

• bbe6cd0 go.mod: upgrade libdns/selectel to v1.2.0, remove replace directive
