/**
 * Provider-neutral session import service (issue #3709).
 *
 * Pipeline: bounded read-only source load → format detection → provider adapter
 * → normalization + fail-closed redaction → head/tail bounding → persistence
 * into a NEW GJC session through the public SessionManager API.
 *
 * The source file is never written, moved, or enumerated. The live session is
 * never touched by this module; callers switch sessions explicitly after a
 * successful materialization.
