Changing ignoredOptionalDependencies previously forced dependency resolution
even when the change only added ignore patterns. Detect monotonic additions,
remove matching optional importer edges, and prune package snapshots that are
no longer reachable. Preserve packages that remain reachable through another
dependency path.
Use the same optimization in the TypeScript CLI and pacquet. Keep removals and
new exclusion patterns on the safe resolution path, and prevent pacquet from
using a pruned lockfile as the seed when ignored-optional settings differ.
Make current-version package-manager pin tests use a static local registry so
release commits can be tested before their version is published.
