Single-click type chooser, popup warmup fix, rename ProcessMemory plugin

- Type chooser popup now opens on single click (no need to pre-select node)
- Fix ~170ms first-open delay by pre-initializing Qt popup subsystem at startup
- Rename ProcessMemoryWindows -> ProcessMemory (already supports Linux)
