Don't insert initial blank line when improving code

[r0man]

Hi Sergey,

first, thanks for Ellama. It's a nice package I'm starting to use as my daily driver.

I think I found an issue:

Ellama inserts blank lines when improving code. Steps to reproduce are:

• Open a new file.
• Enter the following code.

  (defun hello-world ()
  (interactive)
  (message "Hello, world!"))

• Mark the whole buffer M-x mark-whole-buffer.
• Run M-x ellama-code-improve.
• Notice that the improved code inserted into the buffer contains an extra blank line at the beginning.

  ;;; HERE IS A BLANK LINE
  (defun hello-world ()
    (interactive)
    (message "Hello, world!"))

This is due to the ellama--code-prefix matching against the end of line. When using this function to strip off the prefix, an extra blank line remains at the beginning.

I included 2 tests to prevent a regression.

Would you like to merge this PR?

My FSF assignment is in process. I hope to have it done very soon.

Thanks, Roman.
