ouroboros: Add IRM wrapper

Add ouroboros.irm module wrapping the Ouroboros IRM C API, providing
Python interfaces for IPCP lifecycle (create, destroy, bootstrap,
enroll, connect), name management (create, destroy, register, list),
and program/process binding.

Split the monolithic CFFI build into separate _ouroboros_dev_cffi and
_ouroboros_irm_cffi modules, each linking only its required library.

Also includes:
- ouroboros.cli module with higher-level wrappers mirroring CLI tools
- FRCT flag support (set/get) in the Flow API
- FlowPeer event type in FEventType
- QoS defaults updated to match ouroboros source
- Bug fixes: flow_set_snd_timeout typo, flow_set_flags calling
  convention, FlowSet name mangling, fqueue_type return type
- .gitignore, copyright updates, version bump to 0.23.0
