fix: resolve powerline's tmux bindings instead of pinning a Python version

Browse Source 
tmux.conf sourced
  /usr/lib/python3.11/site-packages/powerline/bindings/tmux/powerline.conf
which puts a Python minor version in a path. It was already wrong before this
repository touched anything: beastix runs 3.14, so tmux has been printing that
error there for however long. shron never had the problem because its own
tmux.conf had the line commented out - until the checkout replaced that file
with this copy, and every session there started with the error.

Replacing a deliberately disabled setting with a broken one is the worse of the
two outcomes, and it is exactly what "every machine carries every file" costs
when a file is not actually machine-neutral.

The path now comes from the module itself, so it survives Python upgrades, and
each step exits quietly if something is missing. The Mac has neither powerline
nor tmux and gets nothing.
