revert(store): drop the page-cache hoist from process init

Measurement retired the theory it was built on: the slab installs correctly now
(config_failed=0) and the leak was unchanged, because the cause was thread
heaps never being released rather than page-cache fragmentation.

It also runs at the top of main() for every process, including the launcher,
and the managed reinstall guard went red. A change that fixes nothing it
claimed does not get to stay on a release-blocking PR while a Windows guard is
failing. cbm_store_configure_pagecache remains available for a future attempt
wired ahead of sqlite3_initialize deliberately.
