What does this PR do?

Adds a new copyWithOptions command that allows users to copy messages with customizable formatting options. Users can now select exactly which messages in the session to copy with formatting retained. This does not replace the existing copy command.

• The new copyWithOptions command that enables selective copying of session messages
• Solves the problem where users could only copy entire session transcripts or the last message—now they can choose exactly which messages to export
• Adds a DialogCopyMessages component that provides a keyboard-navigable interface where users can view message previews, toggle selections with spacebar, select all with Ctrl+A, and confirm with Enter
• TUI user interface with keyboard-first navigation (up/down arrows, space, Enter, Ctrl+A)
• Includes unit test coverage validating both the command handler logic and the dialog component behavior

How did you verify your code works?

• Added unit tests for the new DialogCopyMessages component
• Extensive manual testing to see that all the copy commands and different options are working
