Behavior cluster

This PR tightens the experimental node:vm module lifecycle surface around Module, SourceTextModule, and SyntheticModule:

• exposes vm.Module through the manifest/native table so direct calls compile and throw Node-shaped errors
• distinguishes vm.Module() from new vm.Module() error messages and preserves argument side effects before either throw
• aligns vm.Module.length with Node's value
• updates SyntheticModule#setExport() for missing export names to throw Node-shaped no-code ReferenceErrors in pre-link, linked, and evaluated states
• extends the VM module lifecycle parity fixture to cover constructor/call errors, argument side effects, missing export errors, and existing link/evaluate/module request behavior

Why batched

#3132, #3133, and #3322 share the same gated VM module constructors, runtime module handle model, HIR lowering, native table/manifest rows, and test-parity/node-suite/vm/modules/lifecycle.ts fixture. Keeping them together avoids splitting one lifecycle state machine across multiple tiny PRs.

Tests added

• Extended test-parity/node-suite/vm/modules/lifecycle.ts with vm.Module call/construct errors, function arity, argument side effects, and SyntheticModule#setExport() missing-name error cases.

Known limitations and non-goals

• VM module support remains gated by PERRY_EXPERIMENTAL_VM_MODULES.
• This does not implement a general JavaScript module interpreter beyond the deterministic local module semantics covered by the fixture.
• This does not address broad VM Script/context execution, compileFunction, measureMemory, or additional cached-data fidelity outside the existing cached-data fixture surface.
