Browse source 
* Initial plan

* Refactor find_probe() to use std::optional

- Updated tactic_manager.h: Changed return type to std::optional<probe_info*>
- Updated tactic_manager.cpp: Modified implementation to return std::nullopt or probe pointer
- Updated api_tactic.cpp: Changed 2 call sites to use optional checks and dereference
- Updated tactic_cmds.cpp: Changed 1 call site to use optional check and dereference
- Build verified successfully
- Probe functionality tested with Python bindings
