feat(bindings)!: add RVM/Program support across FFI and language bindings (#565)
- FFI: add RVM/Program APIs, execution state accessors, HostAwait handling, and buffer/result helpers in rvm.rs, common.rs, engine.rs. - Compiler: emit HostAwait for __builtin_host_await in function_calls.rs. - RVM tests: add HostAwait regression cases and extend harness for suspend/resume responses in host_await.yaml and mod.rs. - C/C++: add RVM tests/examples and wrapper updates in rvm_tests.c, rvm_tests.cpp, regorus.hpp, plus CMake wiring. - C#: add Program/Rvm bindings, SafeHandle/PInvoke, tests, and example usage in Regorus, RvmProgramTests.cs, Program.cs, and README updates. - Go: add Program/Rvm bindings, tests, and examples in rvm.go, rvm_test.go, main.go. - Java: add Program/Rvm bindings, JNI glue, and examples in lib.rs, regorus, Test.java. - Python: add Program/Rvm bindings and examples in lib.rs, test.py. - WASM: add Program/Rvm bindings and examples in lib.rs, test.js. - Tooling: wire binding tests in xtask and ignore generated Java artifacts in .gitignore.
