Add GitHub CODEOWNERS and branch-protection runbook

[leostar0412]

Summary

• Add .github/CODEOWNERS with per-app owners, core/ and .github/workflows/ ownership, and docs/ reviewers (@snowfox1003, @jonathanMLDev, @wpak-ai).
• Add docs/operations/CODEOWNERS_and_branch_protection.md with steps to require code-owner review and how to verify assignment after merge.
• Refresh docs/operations/README.md to describe operations vs service API and link the new runbook.

Test plan

• Confirm CODEOWNERS syntax / paths look correct on GitHub after merge.
• (Repo admin) Enable Require review from Code Owners on the protected branch if not already on.
• Optional: open draft PRs touching one app path, docs/, and .github/workflows/ to confirm requested reviewers.

Poem

🐰 Hop! A file of owners, neat and fair,

Paths marked true beneath the gardener's care,
Reviews will bloom where guardians stand,
Docs and workflows held by friendly hands,
A tiny hop to keep the repo grand.
