native: typed emit and pyfun build for projects - #158
Merged

Conversation
Project lowering now receives each module's resolved types (already computed in the per-module pass for float literals), so every module's top-level functions are annotated in native mode, and Option/Result spell through the classes a project imports from _pyfun_rt. pyfun build --native accepts a project: every module is built by mypyc in one go and the shared _pyfun_rt.py stays Python. native-bench gains a step that builds examples/modules natively and diffs its output against pyfun run.

project::compile_withalready type-checks each module in topological order (for float literals and codecs); in native mode it now also keeps each module's resolved types and hands them tolower_in_project, so every module's top-level functions get annotations.Option/Resultspell through the classes a project imports from_pyfun_rt(def lookup(key: int) -> Some | None_:).pyfun build --nativefor projects: every module is written to<dir>, all but_pyfun_rt.pygo through one mypyc invocation, and the runtime stays Python (the compiled modules import it like any other module).__main__.pyimports the entry module.native-benchgains a step that buildsexamples/modulesnatively on Linux and diffs its output againstpyfun run.Locally (Windows): the project passes mypy and reaches mypyc's
