sneak 879d41eb2b metrics: rate limit /metrics per client address before Basic Auth (closes #101)
check / check (push) Successful in 1m31s
/metrics is behind a password, and REPO_POLICIES.md requires rate
limiting on password logins. Each client address may now send it 30
requests a minute, counted by httprate before Basic Auth, so failed
logins use up the allowance and a request over it gets 429 without
the password being checked. The address is the one the existing
trusted-proxy logic in internal/middleware works out, with IPv6
addresses grouped by /64; an IPv4 address a proxy reports in
IPv6-mapped form counts as the plain IPv4 address. A Prometheus
server scraping every 15 seconds sends 4 requests a minute.

clawbot f7cc6b42e0 server: limit wildcard CORS to the public routes (closes #100)
check / check (push) Successful in 1m13s
The CORS wildcard was global, so it also covered the Basic-Auth
protected /metrics, which REPO_POLICIES.md forbids, and it allowed
POST, PUT and DELETE, which no route serves, plus the Authorization
and X-CSRF-Token headers. CORS now sits on a router holding only the
public routes and allows GET and OPTIONS with the Accept and
Content-Type headers. /metrics gets no CORS at all.

Both are mounted routers rather than a Group: chi answers OPTIONS on
a Group's route with 405 before its middleware runs, and any method
/metrics does not register would otherwise fall through to the public
router. So every method on /metrics now meets Basic Auth first, and
/metrics/ is served like /metrics.

clawbot 8aaa103956 middleware: add security response headers (closes #98)
check / check (push) Successful in 54s
Adds a SecurityHeaders middleware and registers it globally, right after the request ID middleware, so every route gets the headers, including static files, /metrics and error responses.

It sets Strict-Transport-Security (one year, includeSubDomains), a Content-Security-Policy with default-src 'self', no scripts and frame-ancestors 'none', X-Frame-Options DENY, X-Content-Type-Options nosniff, Referrer-Policy no-referrer and a Permissions-Policy that turns every listed feature off.

HSTS is sent on every response, not only over TLS: the service runs behind a TLS-terminating proxy and REPO_POLICIES.md requires the application to send it. Referrer-Policy is stricter than the policy baseline because dashboard URLs can name internal hosts.
