Add --jobs N to xce-build.sh: for meson compile it's passed as ninja's -l N
load-average ceiling (re-checked before every job launch for the whole
build, so it adapts if a concurrent session in this shared sandbox loads
the system mid-build), and as a job-count ceiling (-j/--num-processes,
-p) for meson test/go test, which have no load-average equivalent. No
default -- omitting it preserves prior auto-parallelism behavior exactly.
The xce-build skill now computes N live at invocation time from nproc,
/proc/meminfo's MemAvailable, and /proc/loadavg, rather than a fixed
constant, and passes it through.
