Deferred TODOs: QMK HID-descriptor mapping (unused) + device-enumeration workaround (#254)

[malpern]

Tier: 3 (minor / deferred-by-design)

From the pre-release feature-gap audit. Two unrelated deferred TODOs tracked together for cleanup.

Items

1. QMK HID-descriptor key identification — declared but not used by the current keymap-based flow.
   • Sources/KeyPathAppKit/Services/Import/QMKKeycodeMapping.swift:299 — "TODO: Wire up for future HID descriptor-based key identification (not used in current keymap-based flow)."
2. Device-enumeration workaround — a temporary workaround pending an upstream fix.
   • Sources/KeyPathAppKit/Services/Devices/DeviceEnumerationService.swift:58 — "TODO: Remove once upstream lands. Tracked by Remove fake device fixtures once macOS multi-device support lands #254."

Action

No release impact. Remove/finish once the respective upstream work lands.
