closes #666

Summary

Adds a #[cfg(test)] pub fn current_scope_stack() helper to ReentrancyGuard that returns the active scope chain, enabling integration tests to assert correct nesting and detect accidental cross-scope leakage.

Changes

  • reentrancy_guard.rs: Added current_scope_stack(env: &Env) -> Vec<Symbol> — compiles only under #[cfg(test)], reads the persistent lock map, filters for held scopes. Zero production surface change.

  • Two tests updated to use the helper instead of individual is_locked assertions:

    • different_entrypoint_scopes_do_not_block_each_other — validates full stack depth (0→1→2→1→0) across nested with_guard on distinct scopes
    • with_guard_rejects_nested_same_scope_invocation — validates stack is [scope] after rejection and [] after outer guard exits
  • Vec import gated behind #[cfg(test)] — zero unused-import warnings in production builds.

Verification

  • Vec import gated to cfg(test)
  • Two pre-existing tests adopt the helper
  • No public surface change for production build
