Merge main into agent/fix-requirements-decode

Resolve the pypi_requirements.rs conflict with #1168, which moved the
requirements walk onto ProjectView: keep this PR's per-caller decode
step (strict UTF-8 for the planner, pip's decoding for the include
listing) by reading bytes through view.read_bytes and decoding them,
and drop the now-unused read_regular_to_bytes import.
