Summary by cubic
Adds session region controls so apps can request a region and read the region that served the session. Accepts any region string (see docs for available regions); rejects invalid
region_policyvalues and requiresregionwhenstrict.SessionOptions.region(string) andregion_policy("preferred"|"strict"), serialized asregionandregionPolicy; invalid policies raiseValueError.regionparsed intoSessionInfo.region(string) and exposed viaAnamClient.regionandSession.region(unrecognized values returned as-is).Written for commit b8440e4. Summary will update on new commits.
