fix(pollux): add exp/nbf validation and fix error logging in SDJWT.verify
Fixes #553 — replaced console.log with silent catch in verification error path, consistent with JWT.verify behavior. Fixes #554 — added exp and nbf temporal claim validation per RFC 7519 §4.1.4 and §4.1.5. SDJWT.verify now returns false for expired or not-yet-valid credentials. Changes: - Check exp claim before signature verification; return false if expired - Check nbf claim before signature verification; return false if too early - Remove console.log(err) from catch block (was leaking error details) - Change import from type-only to value import for Domain (needed for runtime access to JWT.Claims enum) Signed-off-by: abhigyan1102 <[email protected]> Signed-off-by: Abhigyan Singh <[email protected]>
