fix: Swap print keybinding and add confirmation prompt

Print operations are now safer and more intuitive:

Keybinding changes:
- C-; b p → copy file path (safe, common action)
- C-; b P → print to PostScript (dramatic, requires shift)

Print function improvements:
- Add y-or-n-p confirmation before printing
- C-u prefix skips confirmation and enables color printing
- Prevents accidental waste of paper/toner

Serves V2MOM Values:
- Intuitive: Dramatic actions require shift key
- Intuitive: Prevents muscle memory mistakes
- Simple: Reliability through confirmation

Also updated docs/NOTES.org with Makefile availability note.

Closes inbox items from emacs-inbox-zero session (2025-11-03).
