docs: update README Learn More links to point to in-repo docs

[areporeporepo]

Summary

Replace external docs.nvidia.com/nemoclaw links in README.md with relative paths to the in-repo docs/ directory. The external links were valid but outdated since PRs #911 and #603 added the corresponding documentation pages to the repository.

Changes:

• Customize Network Policy link → docs/network-policy/customize-network-policy.md
• CLI reference link → docs/reference/commands.md
• All Learn More section links → their docs/ counterparts

OpenShell external links (Policy Schema, Sandbox Policies) are intentionally preserved since they reference a different repository.

All linked docs/ files verified to exist.

Closes #968

Poem

🐰 Links once distant, now are near,
The docs hop closer, crystal clear,
From distant NVIDIA clouds they came,
To local markdown, home to claim,
A tidy README, updated right! 📚✨
