Disable auto-compile until CEK fallback is robust

The vm-compile replaces Lambda values with NativeFn wrappers.
When the VM can't execute (missing env vars, unsupported ops),
it falls back to cek_call. But cek_call needs proper Env values
that the snapshot doesn't provide.

Fix needed: VM closures must capture the LIVE env (not snapshot),
or the CEK fallback must construct a proper Env from the globals.
Disabling until this is resolved.
