feat: upgrade buttplug package to protocol v4 and WASM v10

Upgrade the buttplug TypeScript client from class-based v3 protocol to
interface-based v4 protocol, and the Rust/WASM server from the monolithic
buttplug 9.0.9 crate to the split buttplug_core/buttplug_server/
buttplug_server_device_config 10.0.0 crates.

TypeScript changes:
- Messages are now plain interfaces with msgId()/setMsgId() helpers
- ActuatorType → OutputType, SensorType → InputType
- ScalarCmd/RotateCmd/LinearCmd → OutputCmd, SensorReadCmd → InputCmd
- Client.ts → ButtplugClient.ts, new DeviceCommand/DeviceFeature files
- Devices getter returns Map instead of array
- Removed class-transformer/reflect-metadata dependencies

Rust/WASM changes:
- Split imports across buttplug_core, buttplug_server, buttplug_server_device_config
- Removed ButtplugServerDowngradeWrapper (use ButtplugServer directly)
- Replaced ButtplugFuture/ButtplugFutureStateShared with tokio::sync::oneshot
- Updated Hardware::new for new 6-arg signature
- Uses git fork (valknarthing/buttplug) to fix missing wasm deps in buttplug_core
