configuring the runtime from a fresh SessionCreateRequest. ModeSessionContext Narrow wrapper around Session that mode plugins use to
initialize, restore, and extend their per-session state.

overflow recovery, manual /compact, …). ModeNativeToolsPlugin ModeProtocolDriverPlugin Singleton plugin slot that owns the ProtocolDriverHandle and
associated preamble (prompt text, tool surface, sync/async flag)
for a given execution mode. Mode-specific crates
(lash-mode-standard, lash-mode-rlm) register one implementation
each; the runtime picks the one whose mode_id matches the session
policy’s execution mode, falling back to build_mode_preamble
when no plugin claims the slot. ModeSessionPlugin Session-scoped plugin that initializes, restores, and extends mode
state across a session’s lifecycle. External mode crates implement
this via context wrappers (ModeSessionContextModeRuntimeContextSession/LashRuntime internals — the context narrows what a
plugin can poke at to the capabilities any execution mode
reasonably needs. PluginAction PluginFactory Registers a plugin with the runtime and produces a per-session
SessionPlugin instance for each new session.
