_nb_ensure_bundled_npm_range ran only at the tail of
_nb_install_bundled_node, so it fired just after a tarball was unpacked.
ensure_node's reuse rung returns before reaching it, leaving an existing
managed tree on whatever npm its Node major bundled.
That strands a real install: the upgrade is best-effort (`|| true`), so
one offline run leaves an at-target Node 26 tree carrying npm 11.17.0 —
below the root package.json's `engines.npm` floor of >=12, fatal under
.npmrc's engine-strict. Heal does not cover it either; the tree is at the
target major and every binary passes --version, so
_nb_managed_node_needs_heal correctly reports it healthy. Re-running the
installer, the documented recovery, never repaired it.
install.ps1 already had this right: Update-ManagedNpm is called from both
branches that yield a managed tree, including the reuse path. This is the
POSIX side of that same call site.
Reproduced on a seeded node-26.5.1/npm-11.17.0 tree: before, ensure_node
left npm at 11.17.0 and `npm ci` died with EBADENGINE; after, it upgrades
to 12.0.2 and `npm ci` installs 208 packages. An already-in-range tree
costs one --version probe (~0.13s), and the system-node path is unchanged.
