kevinveenbirkenbachandClaude Opus 4.7 80c396b839 refactor(env+install/spot): collapse python/venv resolution into shell SPOT
Pulls VENV/PYTHON/PIP/PYTHONPATH out of the dotenv handler pipeline
into scripts/meta/python/detect.sh. load.sh now sources detect.sh and
prepends ${VENV}/bin to PATH above the INFINITO_ENV_LOADED guard, so
every BASH_ENV re-entry re-resolves PYTHON the moment a venv
materialises mid-chain — the same fix as b79ed2869 but at the SPOT,
which retires the reload-trick from ansible.sh, python.sh and
pre-commit.sh.

Also renames INVENTORY_VARS_FILE → INFINITO_INVENTORY_VARS_FILE under
the new env-prefix lint, drops the 5 dead INFINITO_ENV_*_LOADED unsets
left over from the multi-loader era, and adds a lint guarding the
INFINITO_ prefix invariant on env/*.env keys.

# 🐍 Virtualenv bootstrap & setup
#
# This script is responsible for creating the Python virtualenv
# used by the entire Infinito.Nexus toolchain.
#
# Important design rule:
# ❗ The venv Python interpreter CANNOT be used before the venv exists.
# ❗ Therefore we must bootstrap using system python3 first.
#
# Lifecycle:
# 1) Use system python3 to create the venv
# 2) Afterwards, Makefile provides PYTHON=${VENV}/bin/python
# 3) All tooling runs inside the venv from then on
#
# This avoids chicken-and-egg failures in CI and on fresh machines.
