Rename from Bake framework to Bun Rendering API

Update documentation to correctly refer to this as the "Bun Rendering API"
rather than "Bake framework". This better reflects that it's a rendering
system/API rather than a full framework.

Changes:
- Rename title from "Bake: Full-Stack Web Framework" to "Bun Rendering API"
- Replace "Bake" references with "Bun Rendering API"
- Replace "framework" with "rendering system/API" in descriptions
- Update variable names from "customFramework" to "customConfig"
- Clarify this is an experimental rendering API
