Alex Dunmow 9a4394a07c feat(auth): X-Bn-Verified-Captcha trusted header + CaptchaVerified helper
The host verifies (and consumes) a request's cap-token against its
stateful captcha server before wasm dispatch and stamps this header;
guests enforce captcha by checking CaptchaVerified, fail closed.
Included in AllTrustedHeaders so the host's strip-then-stamp loop
makes it unforgeable, like the identity headers.
