Pull Request Overview

This PR improves type safety across the terminal codebase by replacing uses of the any type with more specific types (unknown or proper generic type parameters). The main change adds a default type parameter to the IProcessProperty interface, allowing it to be used without explicit generic arguments while maintaining type safety through indexed access types.

• Updated IProcessProperty<T> interface to have a default type parameter (T extends ProcessPropertyType = ProcessPropertyType)
• Replaced any with unknown in function parameters and return types across multiple terminal-related files
• Added type assertions where needed to maintain type safety after removing explicit generic parameters
• Removed multiple files from the eslint @typescript-eslint/no-explicit-any ignore list
