…runfiles `pyi_deps` are documented as build-time only dependencies for type checking and static analysis. Previously, `create_py_info` merged `pyi_deps` targets using `py_info.merge()`, which caused all transitive sources from type stubs and their dependencies to be placed in `PyInfo.transitive_sources` and included in downstream binary/test runfiles. This change updates `create_py_info` to only propagate `imports`, `transitive_pyi_files`, and `transitive_original_sources` from `pyi_deps`, preventing them from leaking into runtime runfiles. Adds unit tests verifying `transitive_sources` and binary runfiles exclusion.

pyi_depsare documented as build-time only dependencies for type checking and static analysis, but currently leaks into the runfiles.Before:
create_py_infomergedpyi_depstargets usingpy_info.merge(), which caused all transitive sources from type stubs and their dependencies to be placed inPyInfo.transitive_sourcesand included in downstream binary/test runfiles.After:
create_py_infoonly propagatesimports(for module import resolution during type checking),transitive_pyi_files, andtransitive_original_sourcesfrompyi_deps. Adds unit tests verifyingtransitive_sourcesand binary runfiles exclusion.Tested: in our repo using
rules_pythonandpyi_depsfor type checking, this reduced the runfile tree size with 20M for a samplepy_test.
