Move instruction profiling to a dedicated thread

[mohitejaikumar]

Implements #320

1. Added start_profiling_runloop that spawns a long-lived "Instruction Profiler" thread via hiro_system_kit::thread_named.
2. ProfilingJob struct - Packages all data needed for profiling (cloned SVM, transaction, accounts, etc.) to send across the thread boundary.
3. Added Option<Sender<ProfilingJob>> to SurfnetSvm.
4. Refactored fetch_all_tx_accounts_then_process_tx_returning_profile_res to send profiling jobs to the dedicated thread, execute the transaction on the current thread, then collect profiling results — running both in parallel.
5. setup_profiling helper - Extracted profiling channel setup into a reusable function called from both start_local_surfnet_runloop and tests.
6. Added Clone to IndexedLoadedAddresses and TransactionLoadedAddresses to enable moving data into the profiling job.
