docs(blog): rename RSC post to lead with "Who Owns the Tree?"

[tannerlinsley]

Summary

• Renames draft post rsc-is-a-protocol-before-it-is-an-architecture → who-owns-the-tree-rsc-is-a-protocol-not-an-architecture
• Updates title to "Who Owns the Tree? RSC Is a Protocol, Not an Architecture"
• Renames the matching asset folder under public/blog-assets/
• Adds redirect_from for the old slug so any preview links keep working

Test plan

• Visiting the old slug redirects to the new one
• Both SVG figures still resolve under the new asset folder
