HHY Language 1.3.2

HHY v1.3.2

HHY v1.3.2 stabilizes the internal Bytecode VM boundary and makes the AST
semantic oracle a permanent regression gate for the v1.3 train.

Stabilized internal boundary

• Introduces src/bytecode_runtime.h as the only preparation boundary visible
  to the semantic Runtime.
• Moves compilation, fault injection, verification, structural frame planning,
  and Chunk lifetime ownership into src/bytecode_runtime.c.
• Prevents runtime.c from directly accessing HhyBytecodeChunk or calling the
  Compiler, Verifier, or execution planner.
• Versions this internal contract with
  HHY_BYTECODE_RUNTIME_BOUNDARY_VERSION = 1.
• Extends static Runtime governance so boundary bypasses fail CI.

Continuous semantic oracle

• Runs the complete language/runtime suite once with AST and once with Bytecode.
• Preserves deterministic malformed-Bytecode fault injection.
• Runs official real workloads under both engines and records capability skips.
• Uploads benchmark, default-engine decision, and workload evidence from CI.
• Keeps AST as the default because the CPU performance switch gate remains unmet.

Compatibility

• No v1.0 language semantic, extension protocol, lockfile, diagnostic, or exit
  status contract changes.
• No persistent Bytecode format, external loader, JIT, Native ABI, or public VM ABI.
• --engine ast remains an explicit fallback and semantic oracle.
