Interface JuliaScopeOptions

Scope mode determines how Julia objects are tracked and released.

• 'default': Scope-based with concurrent async support. Thread-safe, handles parallel scopeAsync().
• 'safe': All objects use FinalizationRegistry. Safe for closures but non-deterministic release.
• 'perf': Lock-free stack-based. Fastest but ONLY for single-threaded, strict LIFO scope order.

WARNING: 'perf' mode is NOT safe for:

• Concurrent Julia.scopeAsync() calls
• JuliaTask parallelism
• Non-LIFO scope disposal order
