name: start_session

description:
Optionally create or return a lifecycle session before acting. For multi-call work, prefer a short public `session` label and repeat it on every call that accepts it; an omitted value uses the authenticated transport lease's implicit session instead. This tool is optional because an ordinary action can create or reuse a named run directly. Use it to set the initial cursor theme before acting or to revive a public name after it has ended; ordinary actions never revive ended names. `capture_scope` is deprecated compatibility input; new callers select window or desktop modality per action. Idempotent.
