v0.31.0

Added:

• Update default CPython distributions to 20261026
• Update default PyPy distributions for Python 3.11 and 2.7 to 8.0.1, requiring glibc 2.28 or newer on Linux

Fixed:

• Update TLS trust dependencies to address a certificate authority compromise affecting binaries built with the bundled lockfile, including cargo build --release and cargo install pyapp --locked. Builds using cargo install pyapp without --locked already resolve the fixed dependencies.
