Set up kernel compatibility and safety test pipeline for eBPF agent

[jundorok]

Summary

We need a simple release gate to make sure our eBPF agent is safe to deploy across supported kernels and distros.

We should not try to support “all kernels”.
We should define a small supported matrix and test those continuously.

Goal

Build a CI pipeline that verifies:

• the eBPF object can load
• required features exist on the host
• attach/detach works cleanly
• the agent does not leave broken state behind
• basic runtime overhead is acceptable
• a report is generated for each kernel lane

What we need:

self-hosted runners for each kernel/distro lane we want to validate
optionally ARC or a runner pool if we want to scale this later
Initial scope

Support a small matrix first:

Ubuntu LTS
Debian stable
RHEL/Rocky
Amazon Linux
x86_64 first
arm64 later

What to test

TBD
