fix: install hermes-agent from pip so build-time TTS patch works

Browse Source 
The Dockerfile starts from debian:stable-slim, not from the official
Hermes image. Without installing hermes-agent from pip, there is no
tools/tts_tool.py in the image at build time, so the patch script
crashes with FileNotFoundError.

Adding hermes-agent to uv pip install gives us tts_tool.py in the
venv site-packages, so the COPY+RUN patch step works cleanly.

Also keep the runtime fallback in fix-permissions.sh for cases where
the volume's site-packages differ from the image.
