Recompile all 26 .sxbc with define-library wrappers + fix eval/JIT

All 26 browser modules recompiled with define-library/import forms.
Compilation works without vm-compile-adapter (JIT pre-compilation
hangs with library wrappers in some JIT paths — skipped for now,
CEK compilation is ~34s total).

Key fixes:
- eval command: import-aware loop that handles define-library/import
  locally without touching the Python bridge pipe (avoids deadlock)
- compile-modules.js: skip vm-compile-adapter, bump timeout

2621/2621 OCaml tests passing.
