perf(resolver): memoize the interned package.json path Dependency tracking re-hashed and re-interned the same package.json path on every resolution that walks through its directory. Keep the interned handle on PackageJson, which is already shared per directory, so registering the dependency is a refcount bump instead of an intern-table lookup. path is now the interned handle itself instead of a PathBuf plus a memoized interned copy, so there is a single representation: readers keep working through Deref<Target = Path>, and the two error constructors that need an owned PathBuf convert on the cold path. PackageJson::parse now fills every field in one place, which also removes the Default impl that could only build an invalid placeholder (empty path, null JSON mirror).

perf(javascript): borrow the parser plugin drive instead of cloning it per node Plugin hooks receive `&mut parser`, so hot paths cloned the drive `Rc` before every hook call to satisfy the borrow checker, then dropped it again. The drive is immutable and outlives the parser, so let `scan_dependencies` own it and give the parser a `&'parser JavaScriptParserPluginDrive` field: the hook call sites still hand out a detached borrow, without a raw pointer or an `Rc`. Measured with Callgrind on a production application's page-level fixture (make window, no minification): the make-phase self IR drops by ~3.3M (≈ −0.5%), and the `Rc` drop disappears with the handle.
