Use Arc<[u8]> for Binary sources in the portable module tree and renderer.
Cloning fetched sources and module-map entries now shares the original bytes
instead of copying the entire Wasm file. Compilers still borrow &[u8].
Preserve the existing policy that retains Wasm raw bytes in the module map
after compilation. Keep this change separate from synthetic text ownership.
Exercise both evaluation and source import phases through the actual module
tree compile path. Verify identical byte addresses, one remaining strong
owner after fetch temporaries are dropped, and release on document disposal.
The new regression fails with the previous Vec<u8> representation.

JSON/CSS compilation retained independent copies in the module map and the
synthetic module record. Share immutable text with Arc<str> across fetched
sources, the portable module tree, and synthetic evaluation records instead
of copying String buffers during cloning and registration.
Release the module-map source after successful JavaScript/JSON/CSS compilation.
Make fetched-source retention an exhaustive ModuleKind policy, preserving Wasm
and text-preload source semantics. Context lookups remain weak record references.
Cover the actual module-tree compile path: the record keeps exactly one strong
reference to the original text allocation after fetch temporaries are dropped,
and destroys it when disposed. Verify record clones share the same source and
Wasm entries retain their binary source.

Retain Error and WebAssembly CompileError/LinkError kinds when translating module failures into and out of the shared module tree. Cover cached graph failures and malformed Wasm import rejection, including author-replaced constructors.
