fix(appkit): forward execArgv so the detached typegen worker runs under tsx

The non-blocking CLI spawned its background worker as `node <argv[1]>` without
the parent's node/loader flags. Run from source via tsx, argv[1] is a .ts file
that plain node can't parse, so the worker died silently (detached + stdio
ignore) and the degraded types never refreshed -- the queries appeared to never
run. Forward process.execArgv, which carries tsx's --require/--import loader
flags (and is empty for the built bin, so production is unaffected), so the
worker runs under the same runtime as the parent.
