Caddy directives

Olympus's Caddyfile uses these directives. Each has its own page with the Olympus-specific usage.

Directive	Purpose
`reverse_proxy`	Proxy requests to upstream services.
`rate_limit`	Per-IP request throttling. Requires the caddy-ratelimit module.
`tls`	TLS termination with automatic Let's Encrypt or DNS-01 ACME.
`header`	Set or remove HTTP headers on requests / responses.
`respond`	Return a static response without proxying.
`redir`	HTTP redirect.
`encode`	Response compression (gzip, zstd, br).
`log`	Access logging.
`handle`	Route requests based on matcher; mutually exclusive in a host block.
`@matcher`	Named request matcher referenced by handlers.
