}Expand description
Session-scoped plugin that initializes, restores, and extends mode
state across a session’s lifecycle. External mode crates implement
this via context wrappers (ModeSessionContext,
ModeRuntimeContext) so they don’t need direct access to
Session/LashRuntime internals — the context narrows what a
plugin can poke at to the capabilities any execution mode
reasonably needs.
