Suriyakumarvijayanayagam 92573e9067 The installer, run on a clean machine, found two bugs in itself
Ran behavision-setup in a fresh Linux container: Python 3.12, nothing
else, the release contents mounted read-only the way Program Files or a
shared drive would be. It failed, and then it failed differently, and
both failures would have been the client's first experience.

1. `pip install <folder>` makes setuptools write behavision.egg-info
   INTO the folder. The folder is read-only wherever a release is
   sensibly unzipped, so: "could not create 'behavision.egg-info':
   Read-only file system". The release now ships a wheel - pure Python,
   buildable anywhere, nothing to build on the shop PC, and pip never
   touches the unzipped folder. Source stays as a fallback and is copied
   somewhere writable first.

2. The engine's paths.py knows two worlds - frozen (ProgramData) and a
   checkout (the repo root) - and a pip-installed engine is neither. It
   resolved its state root to site-packages: database there, camera
   list there, and its generated API credential in a folder the app
   never reads, while the app looked in ProgramData. Every call would be
   401 on a stock install, with nothing in either log saying why. The
   same disease as the Mac checkout two days ago, now in production
   shape.

   engine.ChildEnv is the one place the engine's environment is built,
   used by the desktop app, the headless agent and the installer's own
   smoke test. It passes BEHAVISION_DATA_DIR = this process's state
   root, which paths.py honours ahead of every other rule, so the two
   halves agree by construction however the engine was installed.

   It also seeds config/default.yaml into the state root: a package in
   site-packages has no config beside it to seed from.

Re-run on the same clean container: seven steps, all pass, models
downloaded, engine started and answered, and its data/ landed beside
agent.json - not in site-packages.
