refactor: remove dead descriptor-driven mechanisms (no remaining consumer)
Drop code whose only consumer was a retired runtime: hostBehaviors readers for agentFileExtension, localTargetIsProjectRoot, sharedHooksDirName, skillsManifestPrefix and skipCodexSkillsManifest; the empty NON_REGISTRY_CONFIG_HOME_DESCRIPTORS array and live-config-guard plumbing; the empty RUNTIME_NOTE_AUDIENCE_BY_HEADING filter; the unused resolveVersionFrom export; and the WINDSURF_SESSION_ID workstream session key. Delete tests that only exercised those mechanisms.
