Note

Introduce proactive rebuild for Wasm VM and plugin handles (replacing doRecover), add rebuild flag and cleanup on destruction, and correct WASI path_rename signature.

• Runtime/Core:
  • Add rebuild flow: rename WasmHandleBase::doRecover/PluginHandleBase::doRecover to rebuild and wire new callbacks.
  • Introduce WasmBase::should_rebuild_ with shouldRebuild()/setShouldRebuild() to support proactive rebuild; update recover callbacks to honor/reuse or recreate accordingly and add error logs.
  • Call clearWasmInContext() in WasmBase destructor to prevent stale context references.
  • Minor refactors/formatting in restricted callback setup and logging.
• WASI/API:
  • Fix wasi_unstable_path_rename signature to include new_path_len and update declaration/registration macros.
  • Minor comment/formatting tweaks; keep stubs behavior consistent.
• Tests:
  • Update tests to use rebuild API and validate rebuild/reuse behavior across plugin/VM failures.
