Rehome the wire serialization helpers under protocol ownership so the module name reflects its real role instead of simulator-era naming.
- rename sim/wire header to protocol/wire_codec
- rename sim/wire implementation to protocol/wire_codec
- keep behavior and byte layout unchanged

Replace hand-rolled argument parsing with CLI11-backed parse paths for streamer runtime config and simulator runtime options.
Simulator help text is now generated from CLI11 app definitions to keep parser/help output in sync, while preserving legacy validation messages and exit semantics used by automation.
This commit introduces the full downstream runtime implementation needed to ingest, transform, and publish streams.
It preserves the original upstream request boundary by packaging the entire cvmmap-streamer module (build config, public API, protocol and IPC glue, and simulator/tester entrypoints) in one coherent core unit.
Keeping this group isolated enables reviewers to validate runtime behavior and correctness without mixing test evidence or process documentation changes.
