A failed npm install during `hermes update` prints "Fix npm and re-run
`hermes update`" -- but re-running on a current checkout hit the
"Already up to date!" early return before the Node refresh, so the
repair advice could never work and node_modules stayed stale forever
(#77211).
The commit_count == 0 path now runs the Node refresh through
_repair_node_deps_on_current_checkout. _update_node_dependencies
self-gates on the lockfile hash, which is only recorded after a
SUCCESSFUL npm install (and re-trips when node_modules is missing or
the web toolchain never landed), so healthy installs pay one hash
check and nothing else; a previously failed install actually repairs.
A clean refresh pairs with the web build like every other call site;
a failed one surfaces the fix-npm hint instead of "Already up to
date!".
Fixes#77211.
