v3.0.2

Added

• The PEP 561 py.typed marker now ships inside the pev_synth wheel, so
  downstream type checkers (mypy, pyright) pick up ev-flow's inline type hints
  when the package is installed from PyPI.
• ATTRIBUTION.md is now included in the source distribution, documenting every
  upstream data source's license and the required SPEECh (CC BY 4.0) and U.S.
  Census Bureau Data API notices.

Fixed

• Cross-platform correctness: all meta.json, validation_report.json, and
  validation_report.md reads and writes in api and validator now pass an
  explicit encoding="utf-8", instead of relying on the platform default
  encoding. This makes bundle metadata and validation reports round-trip
  identically on Windows (where the default was previously cp1252).
