module style 5: add introspective constants

[prozacchiwawa]

Note

High Risk
High risk because it changes core code generation, environment shaping, and constant evaluation ordering for module compilation, which can affect determinism and correctness of produced CLVM across many programs.

Overview
Enables module-style introspective constants by introducing ModulePhase (common phase, standalone export phase, and constant-evaluation phase) and threading it through CompilerOpts and PrimaryCodegen, changing how env shapes are built, finalized, and how exported functions are lambda-wrapped.

Reworks constant and helper generation in codegen to produce a stable env first, then evaluate module constants in a dependency-driven order (with convergence checks), and updates deinlining/funcache behavior to include constant dependencies for module compiles and to document cache-key invariants.

Adds new module test fixtures and extensive new tests for determinism, cache hit/miss behavior, @ form validation, and constant-cycle failure, plus a new GitHub Actions workflow that builds/tests this repo against chia-gaming (including a tempfile downgrade and helper scripts to patch and run chia-gaming’s CLSP test suite).
