Mathias Beaulieu-Duncan 69e29d4f6d feat(altcha): add Svrnty.CQRS.Altcha core check + DI
The Altcha authorization check, plugged into the
ICommandAuthorizationCheck / IQueryAuthorizationCheck seam.

Behavior
- Self-applies: returns Allowed for any request whose type isn't
  decorated with [Altcha]. No-op for the 99% of endpoints that don't
  need PoW.
- Reads ctx.Items["mobile_attested"] for Phase 3 bypass when the
  attribute's AllowMobileAttestationBypass is true.
- Pulls the solution off the request via IHasAltchaSolution and
  delegates verification to IAltchaVerifier (resolved per-call from
  the request scope, so any verifier lifetime works).
- Stashes a diagnostic reason in ctx.Items["altcha_reason"]
  (missing / misconfigured / invalid / replayed / expired / etc.)
  for downstream middleware to surface in error responses.
- Singleton itself — stateless; one instance shared via factory
  registrations under both check interfaces.

AddSvrntyAltcha() registers the check. The verifier is provided by
a transport-specific module (e.g. Svrnty.CQRS.Altcha.Grpc, next).
