- Line 11: Replace the placeholder in the VM error module with the
diagnostic-link behavior, integrating it into the VM error construction or
formatting path so emitted error messages include the appropriate diagnostic
link. Use the surrounding error types and formatting logic in error.rs to
preserve existing message content while adding the link.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Set the VM error mode before validation.
VMError formatting reads the thread-local configuration. optimize_bytecode_internal checks Capability::Control before setting this VM's mode. call_exported_internal does not set the mode before its capability, export, or function validation. After another VM runs on the same thread, these errors can use stale diagnostic_links and other formatting flags.
Move set_mode(...) before require(Capability::Control) in optimize_bytecode_internal. Call set_mode(...) at the start of call_exported_internal, before its validation checks.

option before adding it to LightVM.DEFAULTS.

declarations to expose withDiagnosticLinks(en: boolean), delegating to
