Yuzerion c00854a124 feat(autocert): add multi-certificate support (#185)
Multi-certificate, SNI matching with exact map and suffix tree

Add support for multiple TLS certificates with SNI-based selection. The
root provider maintains a single centralized SNI matcher that uses an
exact match map for O(1) lookups, falling back to a suffix tree for
wildcard matching.

Key features:
- Add `Extra []Config` field to autocert.Config for additional certificates
- Each extra entry must specify unique `cert_path` and `key_path`
- Extra certs inherit main config (except `email` and `extra` fields)
- Extra certs participate in ACME obtain/renew cycles independently
- SNI selection precedence: exact match > wildcard match, main > extra
- Single centralized SNI matcher on root provider rebuilt after cert changes

The SNI matcher structure:
- Exact match map: O(1) lookup for exact domain matches
- Suffix tree: Efficient wildcard matching (e.g., *.example.com)

Implementation details:
- Provider.GetCert() now uses SNI from ClientHelloInfo for selection
- Main cert is returned as fallback when no SNI match is found
- Extra providers are created as child providers with merged configs
- SNI matcher is rebuilt after Setup() and after ObtainCert() completes
