* feat!: add Rego Virtual Machine (RVM) implementation This commit introduces a register-based virtual machine for executing Rego policies with bytecode-style instructions. Unlike the existing tree-walking interpreter, the RVM compiles policies into instruction sequences that operate on virtual registers, offering better performance and optimization potential. Core Components: Instruction Set Architecture: - Define instruction types for data operations, control flow, and builtins - Implement instruction parameter encoding and display formatting - Add instruction parser with comprehensive test coverage Virtual Machine Engine: - Register-based execution model with program counter management - Loop execution supporting iterators, comprehensions, and quantifiers - Function call handling with argument evaluation and context management - Rule evaluation with default value resolution and virtual data support - Arithmetic and comparison operation implementations Program Representation: - Program listing builder with instruction sequencing - Rule tree construction for organizing policy rules - Binary and JSON serialization for compiled programs - Recompilation support for program modification Testing Infrastructure: - Extensive YAML test suites covering all VM features - Rust unit tests for VM execution and instruction parsing - Test suites for loops, comprehensions, builtins, and control flow BREAKING CHANGE: Introduces new VM execution path alongside interpreter Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com> * docs: add detailed RVM architecture references Introduce architecture.md explaining program artifacts, serialization, and runtime subsystems. Document the full opcode catalog in instruction-set.md, including operands, parameter tables, and outcomes. Walk through execution flow, stacks, and operational guidance in vm-runtime.md, tying the runtime to the new architecture docs.
