feat(Hotkey): Persist complete hotkey definition

[maya-trenser]

Context

Changes & Results

This PR updates the registerHotkeys method in HotkeysManager to store the complete hotkey definition when registering a hotkey. Previously, only partial information was saved, limiting the ability to reference hotkey metadata elsewhere in the application.

With this change:

• All parameters from the hotkey definition are retained in the manager.
• Downstream consumers can access the full definition for specialized handling, such as dynamic hotkey management or context-aware logic.

This improves flexibility for handling hotkeys beyond simple key-to-command binding while preserving backward-compatible registration behavior.
