…/emSign CA refresh, Go 1.26.10 The eMudhra/emSign incident (eight compromised intermediates) needs every CA store in the agent refreshed: pip always loads its vendored certifi in addition to the system store, so OS ca-certificates alone is not enough. - NODEJS_VERSION 20 -> 24 (Node 20 is EOL; 24.22.1 ships the fixed root store) - uv 0.10.9 -> 0.13.5 (embedded CA store fix) - pip >= 26.2.2 and certifi >= 2026.10.23 for every uv-managed Python - dnf update ca-certificates in the package layer - GO_VERSION 1.21.13 -> 1.26.10, and the tarball's SHA-256 is verified (ARG GO_SHA256, from go.dev) - drop Python 3.9: EOL, and no pip release with the fix supports it (pip >= 26.1 requires Python >= 3.10). uv is installed, so users can still `uv python install 3.9` - the default Python (PYTHON_DEFAULT_VERSION=3.12, defined once) becomes python3, python and python3-config (an exec wrapper, because the script derives its prefix from its own path), and its console scripts (pipenv, virtualenv, az, pre-commit, ...) are linked into /usr/local/bin, which now precedes /usr/bin on PATH. Before, python3 and these scripts had the agent's libraries only because `--system --python 3.9` resolved to the RHEL platform python3.9. The build asserts python3, its libraries, python3-config, the CLIs, and that dnf still works on the platform python3 - the Python loop now fails the build on the first interpreter that fails; before, `fi;` let a later successful iteration mask an earlier failure - CHANGELOG: the python3/pipenv default under Changed, the Python 3.9 removal under Removed - docs: Node/Python/Go versions, python3, tenv (not tfenv) for 2408

Backport of #1175 (master) to 4.x, same agent and docs diff (cherry-pick; only the CHANGELOG context differs, since 4.x has no #1173 entry). Precedent for direct 4.x fixes: #1096, #1097.
Refreshes every CA store in
jenkins-agent-terraform-2408after the eMudhra/emSign incident and moves Node off the EOL 20 line: Node 24 LTS, uv 0.13.5,pip>=26.2.2+certifi>=2026.10.23per uv-managed Python,dnf update ca-certificates, Go 1.26.10 (SHA-256 verified). Python 3.9 (EOL, no fixed pip) is no longer installed;uv python install 3.9remains available. Behaviour change:python3/python/python3-configare now the default Python 3.12 with the agent's libraries (before: the RHEL platform 3.9), and pipenv defaults to 3.12. The Python CLIs (pipenv, az, ...) are linked onto PATH explicitly, and the Python install loop now fails loudly.See #1175 for details and verification output.
