📝 Walkthrough

Summary by CodeRabbit

• Documentation
  • Updated minimum Kubernetes version requirement to v1.33+ for local deployment setups
  • Added explicit prerequisites for Linux kernel (6.3+), container runtime versions (containerd 2.0+, CRI-O 1.25+), and related components
  • Added warning about required Kubernetes user namespaces configuration for build workflows
  • Added new verification command to check node component versions

Walkthrough

Two getting-started documentation files are updated to raise the minimum supported Kubernetes and kubectl version from v1.32+ to v1.33+. The environment setup guide also adds a user namespaces required warning with component version minimums (kernel, containerd/CRI-O, runc/crun) and a new node verification command.
