style(smolmachines): address PR #83 review comments

- bottle.py:_PTY_RESIZE_SCRIPT docstring: strip the speculative
  cwd-dependence explanation. The real reason to use absolute
  path is just that the wrapper is self-contained; the original
  rationale (tmux pane cwd) was a hypothesis we never confirmed
  and wasn't load-bearing once we found the libkrun race.

- pty_resize.py:main: drop the long comment duplicating
  `_STARTUP_SYNC_DELAY_SEC`'s docstring. Keep a one-liner
  pointing at the constant + the operational note about
  daemon=True.
