Security releases for Python 3.10-3.14

The 2026 Python Language Summit was hosted in Kraków, Poland as part of EuroPython 2026. There were 15 talks covering free-threading, Rust, garbage collection, type annotations, and more.

Lightning talks on a one-time ABI break, safer interruptions, EktuPy (Scratch but Python), an AGENTS.md file for CPython, and a call to read PEP 836.
