Two bugs surfaced by the previous deploy attempt:
1. l4d2host/pyproject.toml still listed `l4d2host.fs` in the explicit
packages= list. After deleting the fs/ package, pip install -e fails
with "package directory './fs' does not exist".
2. The CPU-isolation deploy step uses `nproc` to detect host core count,
but `nproc` honors Cpus_allowed of the calling shell. On a host that
already has the cpuset drop-ins applied (system.slice/user.slice →
AllowedCPUs=0), the SSH login lands constrained to one core and
`nproc` returns 1 — making subsequent deploys think they're on a
single-core box and skip the cpuset writes entirely. `nproc --all`
reports installed processors regardless of affinity, which is what
the deploy actually wants.
