fix(hook): carry the mouse's vendor/product ID onto its uinput mirror

[4ni1ak]

Summary

• On Linux, OpenLogi grabs each physical mouse exclusively and re-injects its events through a paired uinput virtual device. build_virtual_device() never set that virtual device's input_id, so it kept evdev's default sample ID (bus USB, vendor 0x1234, product 0x5678) instead of the real hardware's.
• libinput and desktop environments (e.g. GNOME's per-device mouse settings) key pointer-acceleration profile and remembered pointer speed off the reported vendor/product ID. Every re-injected Logitech mouse looked identical and unrecognized under that ID, so those settings silently fell back to their defaults instead of the ones configured for the actual hardware — matching the "cursor speed too slow, ignores system sensitivity" symptom in [Bug]: MX Master cursor speed is too slow and ignores system sensitivity on Linux #1075.

Changes

• crates/openlogi-hook: build_virtual_device() now copies device.input_id() (bus type, vendor, product, version) onto the VirtualDeviceBuilder instead of leaving it at the uinput default.

Testing

• cargo fmt --all -- --check
• cargo clippy -p openlogi-hook -p openlogi-agent -p openlogi-agent-core -p openlogi-desktop -p openlogi-overlay --all-targets -- -D warnings
• cargo test -p openlogi-hook -p openlogi-agent -p openlogi-agent-core -p openlogi-desktop -p openlogi-overlay
• Not runtime-tested on real Logitech hardware or against a live libinput/GNOME pointer-speed setting — that verification is the maintainer's call; to confirm, grab a mouse under OpenLogi and check udevadm info / libinput list-devices on /dev/input/eventN for "OpenLogi virtual mouse" reports the same vendor/product as the physical device, then compare pointer speed with a per-device system sensitivity setting applied.

Fixes #1075

Confidence Score: 5/5

The PR appears safe to merge; the identifier change preserves the existing protection against capturing OpenLogi's own virtual mouse.

Summary

Updates the Linux uinput mouse mirror to copy the physical device's bus type, vendor, product, and version instead of retaining the default identifier.

• Preserves the virtual-device name and existing self-capture exclusion.
• Leaves event capabilities and passthrough handling unchanged.
• No actionable issues identified. Hardware/libinput behavior was not independently runtime-tested during this review.
