"""pytest root config.

Puts repo root on sys.path so bare-name imports (`import cortex`,
`import server.simulator`, etc.) resolve when running from any cwd.
Pytest usually does this via rootdir detection, but doing it explicitly
matches the bare-name import convention documented in the CLAUDE.md files.
