Ruben FiszelandClaude Opus 4.8 9e6559a6f6 fix(nsjail): raise python download fd limit for --compile-bytecode (WIN-2009) (#9414)
#9393 added `--compile-bytecode` to the uv pip install run inside the
python download nsjail. uv spawns a Python interpreter that compiles .py
files with parallelism scaling to the host CPU count, opening many file
descriptors at once. The download nsjail capped `rlimit_nofile` at 64,
which is exhausted on high-core machines, failing every install with
"Failed to bytecode-compile ... Too many open files (os error 24)".

Low-core VMs never hit the cap, so this surfaced only as a regression on
larger workers after upgrading.

Raise `rlimit_nofile` to 10000, matching the runtime configs
(run.python3 / run.ansible) that already use that value.

Fixes WIN-2009
