/**
 * Single source of truth for the AsyncJobManager endpoint key.
 *
 * A session with an explicit provider session id is keyed by (provider id,
 * transcript path); everything else is keyed by its logical session id. The
 * transcript component is canonicalized so a path alias — symlink, `..`
 * segment, or unresolved relative path — cannot register the manager under one
 * key at construction and look it up under another across a session-identity
 * transition, stranding ownership.
 *
 * Both the SDK constructor and AgentSession's transition rekeying must derive
 * the key here; duplicating the shape lets the two drift apart silently.
