`scripts/install.sh::discard_update_lockfile_churn` and `scripts/install.ps1::Discard-LockfileChurn`
run the same per-directory predicate as `hermes update` did before the previous commit, so an
installer-driven update of a managed checkout (Desktop / bootstrap) reverted the root
`package-lock.json` whenever only `apps/desktop/package.json` was dirty, leaving spec and lock
out of sync for the next `npm ci`. Port the same ownership model: the root lock is kept when the
root manifest or any manifest matching a root `workspaces` glob is dirty; nested lockfiles are
still kept only with their sibling manifest; a manifest outside the graph still does not
protect the root lock.
install.sh reads the globs with sed/grep (no jq dependency) and matches with `case`; install.ps1
uses ConvertFrom-Json and `-like`. Bash side live-A/B'd in a throwaway repo (red on main, green
after; controls unchanged); the PowerShell side is the same shape and could not be executed on
this Linux host (no pwsh).
