Rename package from jwtauth to httpauthjwt to follow ecosystem convention
(repo name = package name, hyphens removed). Bump httpauth dependency from
v0.1.0 to v1.0.0 and rbac indirect dependency from v0.9.0 to v1.0.0.
BREAKING CHANGE: import path unchanged (code.nochebuena.dev/go/httpauth-jwt)
but package identifier changes from jwtauth to httpauthjwt — update all usages
accordingly.
Provides AuthMiddleware (calls httpauth.SetTokenData, accepts Verifier or Signer),
IssueTokenPair (access + refresh tokens as jwt.MapClaims, custom claims at top
level for ClaimsPermissionProvider compatibility), RefreshTokenPair (blacklist
check + rotation + re-issue), and Signer/Verifier implementations for HMAC-SHA256
and RSA-SHA256 including PEM loaders and a public-key-only Verifier for read-only
microservices.
