When LGIddHelper is unavailable, recovery requests could remain
pending until timeout while the virtual monitor stayed connected.
This could leave a logged-out guest without a usable display.
Fall back to departing the IDD monitor for active recovery, then
re-arrive it before normal recovery completes. Serialize monitor
lifecycle changes and preserve recovery ordering across Helper
reconnects, timeouts, and stale responses.
Add a protocol-independent recovery channel outside LGMP so clients can
request a usable guest display even when transport versions differ.
Synchronize recovery state with the helper across driver restarts and
restore the configured topology without persisting temporary changes.
Make CSRWLock own the native lock and provide scoped guards for shared,
exclusive, early-unlock, and non-blocking use.
Replace direct SRW lock management throughout the IDD, input driver,
and helper while preserving the existing lock scopes.
Introduce transport, frame, and control interfaces with an LGMP factory
backend.
Move LGMP and IVSHMEM implementation details under transport/lgmp and
expose direct frame-buffer memory through a neutral capability.
Group the IDD sources and Visual Studio filters by subsystem.
Split the device and swap-chain implementations into focused units,
rename the context classes, and reduce header coupling.
