Move 22 public types (QconnectConnectOptions, QconnectLifecycleState,
QconnectConnectionStatus, QconnectVisibleQueueProjection, the 20-variant
QconnectOutboundCommandType + 5 request payload structs, the 4 admission/
handoff types, the 8 device/session/queue payloads) into a dedicated
types.rs submodule. mod.rs re-exports via `pub use types::*` so external
callers (lib.rs invoke handlers, commands_v2/queue.rs) keep their import
paths.
Pure data and enum-mapping impls only. Two helper methods on
QconnectOutboundCommandType (to_queue_command_type,
requires_remote_queue_admission) become pub(super) since they are only
used from within the qconnect module tree.
mod.rs: 6371 → 6109 lines. types.rs: 273 lines.
