feat(install): add nested/scoped dependency overrides

Browse Source

Support npm nested overrides, yarn resolution paths (`parent/child`),
and pnpm `>` syntax (`parent>child`) to scope overrides to specific
dependency subtrees. This extends OverrideMap with a tree structure
that tracks override context through the dependency graph during
resolution, enabling overrides like `{ express: { bytes: "1.0.0" } }`
to only affect `bytes` when it appears under `express`. Includes
serialization for both bun.lock and bun.lockb formats, version-
constrained parent keys, and multi-level nesting.
