Pull request overview

This PR refactors keyboard key/action handling by replacing the previous Keycode enum-based mapping with a new KeyCode utility and a KeyActionToken model, while extending generated RimeKeyMapping helpers to support synthetic codes for uppercase letters and symbols.

Changes:

• Add synthetic keycode ranges (uppercase + symbols) and lookup helpers to the generated RimeKeyMapping.
• Introduce KeyCode and migrate parsing/display-label logic away from the removed ime/enums/Keycode.kt.
• Update theme YAML preset key send values to match the new keycode/name handling.
