chore: emulator sip_gateway, Makefile targets, full README documentation

- Emulator: add sip_gateway field to all scenarios (auto-trunk creation)
- Makefile: build-agent, build-siptest, emulate-*, siptest-* targets
- README: full documentation with agent section, production deployment
- Project structure update with all components
