Note

Low Risk
Documentation-only change to README.md with no runtime or security impact.

Overview
Adds a new FAQ section at the end of README.md (after the Colophon), packaging onboarding and reference material in one place for readers who skip the long body above.

The FAQ restates what Kernel is, features, Docker and Unikraft install commands, requirements (memory, WebRTC/TURN, Kraft, UKC secrets, VCPUS), use cases, license, and a help/resources table with links to docs, signup, Discord, Twitter, and GitHub issues. Much of this mirrors earlier README sections but uses tables and shorter copy for quick scanning.

Firetiger deploy monitoring skipped

This PR didn't match the auto-monitor filter configured on your GitHub connection:

PRs in the kernel, infra, hypeman, and hypeship repos. kernel is a ~mono repo with many logical services underneath, ensure to focus on the implicated service for the PR

Reason: PR is documentation-only (FAQ section) with no code changes, so does not require deploy monitoring even though it's in the kernel repo.

To monitor this PR anyway, reply with @firetiger monitor this.

FAQ section duplicates content from same file

Low Severity

The entire FAQ section restates information already present earlier in the same README file — "What is Kernel?", "Key Features", "Installation", "Use Cases", "License", and "Help & Resources" all duplicate existing sections. This doubles the maintenance surface in one file, and the build/run mismatch bug already demonstrates how duplicated content drifts out of sync.
