fix(patch): warn when patch update --to targets an uninstalled version

[manzoorwanijk]

npm patch update <pkg> --to <version> finalizes with allowUnusedPatches: true, so a --to version absent from the tree is recorded silently with only a success line. The next plain npm install then fails with EPATCHUNUSED, far from the command that caused it.

Fix

#resolveNewVersion now warns when the validated --to version is not in the installed tree. It stays silent when the lockfile cannot be read (the power-user upgrade path); the command still succeeds.
