refactor(add): Create dedicated addFile function

- Move all file reading and content-inlining logic into a new
  'addFile' function in its own 'add.go' file.
- The main function now calls this to parse a log file and then
  appends the returned chats to the main session.
- This improves separation of concerns and makes the main loop cleaner.
