Code Review

This pull request introduces an optional display_name field to the FileData message in sessions.proto. The review feedback suggests a minor improvement to the comment style and grammar of the new field to ensure consistency with the rest of the file.

The comment style and grammar should be consistent with the rest of the file. Specifically, use a period instead of a colon after 'Optional', capitalize the description, and use the singular 'file' instead of 'files' since FileData represents a single file.

Suggested change

	// Optional: the display name of the files
	string display_name = 3;
	// Optional. Display name of the file.
	string display_name = 3;
