fix: resolve OMEN binary path from repo root as fallback

In dev checkouts where submodules are built in the repo root rather than
vendored into hate_path, OMEN binaries were not found. Introduces _omen_dir
that checks hate_path/omen first and falls back to the repo root omen dir.
Also removes vendor-assets from install/update targets and drops vendored
submodule paths from pyproject.toml package data.
