Description

Update CI workflows to use the new composite actions from Calysto/maintainer_tools v1.3.0, and remove the local zizmor config (the new action ships a bundled fallback).

Changes

• Replace zizmorcore/zizmor-action with Calysto/maintainer_tools/zizmor@v1 in zizmor.yml
• Replace raw github/codeql-action/init + analyze steps with Calysto/maintainer_tools/codeql@v1 in codeql.yml
• Replace manual token/checkout/pip/pre-commit/create-pr steps with Calysto/maintainer_tools/pre-commit-autoupdate@v1 in pre-commit-autoupdate.yml
• Replace just pre-commit --hook-stage=manual with Calysto/maintainer_tools/pre-commit-run@v1 in the static job of test.yml
• Delete .github/zizmor.yml (the new zizmor action provides a bundled config as fallback)
