fix(deploy): drop deleted l4d2host.fs from pyproject + use nproc --all

Browse source 
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.
