20260722 generic clvm

[prozacchiwawa]

Note

High Risk
Large, cross-cutting refactor of the classic compiler, optimizer, and module loader—behavior-sensitive paths where subtle generic/import-export mistakes could change compilation or diagnostics.

Overview
Introduces ClassicAllocator in abstraction.rs as the shared interface for classic CLVM tooling: abstract NodePtr, ASExp, import/export to clvm_rs::Allocator, and ClError(Srcloc, EvalErr) on list/atom construction and traversal errors.

Stage-2 pipeline (compile, optimize, module, helpers, inline, reader, defaults) and shared utilities (sexp, pattern_match, debug, operators) are rewritten to take A: ClassicAllocator instead of &mut Allocator directly. Node handles are passed by reference; allocator.loc is supplied when building atoms/pairs. TRunProgram still runs on the raw allocator via export on inputs and import on results.

do_com_prog / do_optimize now return Result<NodePtr, ClError> (no Reduction/Response wrapper at that layer). FunctionExtraInfo and related debug/symbol dump paths are generic over the allocator type. clvm_rs::Allocator implements ClassicAllocator as identity import/export with a default *clvm* source location.
