feat: add activate.sh + switch submit to PyAuto + PYTHONPATH model

activate.sh

+#!/usr/bin/env bash
+# Activate the shared PyAuto venv and point PYTHONPATH at the canonical
+# PyAuto* source checkouts on the HPC.
+#
+# Mirrors the pattern used by z_projects/euclid/activate.sh and
+# autolens_assistant/activate.sh: pip handles only third-party deps in
+# the venv, while the five PyAuto* libraries are resolved via PYTHONPATH
+# directly from /mnt/ral/jnightin/PyAuto/<repo>. ``HPCPullPyAuto`` then
+# becomes the only mechanism needed to keep PyAuto* current — no pip
+# install of PyAuto* into the venv ever.
+#
+# Usage (inside a SLURM submit or interactive shell):
+#
+#     source /mnt/ral/jnightin/autolens_profiling/activate.sh
+#     python3 searches/nautilus/imaging/mge.py ...
