Add --panel flag to new-split command (#10)

Browse source 
* Add --panel flag to new-split command

Allows splitting a specific panel without changing focus first.

Usage: cmuxterm new-split <direction> [--panel <id|index>]

Example: cmuxterm new-split down --panel 1

* Return new panel ID from new-split command

new-split now returns the UUID of the newly created panel, enabling
reliable chaining of split operations without index drift issues.

Before: OK
After:  OK F2675177-3838-49AF-A1A0-1744C0048E99

Example workflow to create left + 2x2 grid on right:
  RIGHT=$(cmuxterm new-split right | awk '{print $2}')
  BOTTOM=$(cmuxterm new-split down --panel $RIGHT | awk '{print $2}')
  cmuxterm new-split right --panel $RIGHT
  cmuxterm new-split right --panel $BOTTOM
