Marc-André Bombeck 63e8630fcb perf(bench): profile a production boot and the idle heap ...

scripts/bench/boot-profile.ts starts the production build with every role
under the production heap ceiling against the seeded benchmark database,
and records the time to a healthy probe and to a ready worker, every
event-loop stall the process logs, the heap lines, the full collections
from --trace-gc, the main thread's busy stretches during the boot with
their self time by source module (resolved through the chunk source maps),
and one heap snapshot after an idle wait, summarised by node type,
constructor, largest strings and largest retained subtrees.

The baseline on the current runtime: a 753 ms busy stretch at 0.7 s, most
of it the worker graph, and a live heap of 164 to 172 MB after five idle
minutes, of which the query compiler holds about 50 MB and the eight
locale catalogs about 33 MB (32 parsed copies and two 9.7 MB chunk
sources).
