Remote session identity is now cached per host and read through a helper instead of the access-token variable directly.

The remote-session identity resolver, which derives organizationUuid, accountUuid, and emailAddress, now caches its result per host and reads its token through a new internal helper instead of reading CLAUDE_CODE_SESSION_ACCESS_TOKEN directly. This avoids repeated JWT parsing when the token hasn't changed.
