Subject: [PATCH] fix(enrichment): treat .python-version as a Python runtime
 pin for EOL checks

The EOL analyzer and its scheduler gate recognized Node pin files but not
pyenv/asdf's `.python-version`, so PRs that pin Python that way silently
skipped EOL analysis. Parse `.python-version` as product `python` and admit
it through the runtime-pin gate.
