tool to avoid unnecessary string formatting.

The usage command provides:
- Token usage statistics for conversation history and context files
- Visual progress bars with color coding based on usage percentage
- Remaining token capacity information
- Tips for managing context window usage

…and Handlers

This commit implements the bidirectional relationship between Commands and Handlers
by adding the `to_command` method to the CommandHandler trait and updating all
command handlers to implement it. This enhancement:

- Makes the command system more type-safe by using enum variants
- Separates command parsing from execution
- Creates a command-centric architecture with bidirectional relationships
- Reduces dependency on the CommandRegistry
- Prepares for future refactoring where `execute` will be used for a different purpose
