blog: Migrating From The Graph Without a Rewrite

[Jordy-Baby]

New blog post: a side-by-side guide to migrating a subgraph to Envio HyperIndex as a drop-in replacement, with before/after config, schema, and handler code, the Katana production migration, and benchmark numbers.

• Adds blog/2026-06-26-drop-in-subgraph-replacement.md (slug /blog/drop-in-subgraph-replacement)
• Adds hero asset static/blog-assets/drop-in-subgraph-replacement.png

Verified locally: blog page and hero asset both serve 200 on the docs dev server, no broken-link warnings. Blog index regenerates on build.
