module style 3: Standalone change on top of the module resolver pr that introduces the needed changes to read module style inputs, but not tiered constant generation

[prozacchiwawa]

Note

Medium Risk
Touches core compilation/preprocessing flows and changes compiler return types, with new on-disk artifact generation for modules; regressions could affect compilation outputs and dependency tracking across many call sites.

Overview
Adds module-style chialisp compilation alongside existing program compilation. The compiler/frontend now detect module inputs, parse export/import forms, build a dependency graph to identify standalone exported constants, and emit a CompilerOutput::Module containing per-export components plus generated *_hash values.

Extends the preprocessor to support import-based module resolution (including relative module names), compile-file embedding (IncludeProcessType::Compiled), and richer include tracking; CompilerOpts gains file I/O hooks (set_filename, write_new_file, get_file_mod_date) and compilation APIs now return CompilerOutput instead of raw SExp, with call sites updated accordingly.

Adds a large set of new resources/tests/module/* fixtures and stdlib .clinc modules to exercise module imports/exports and hashing behavior, and updates run_coverage.py to pass through extra cargo test args.
