Add Overview: introduction, features, concepts, why KERNEL

[andrewleesteele]

Summary

Top layer of the guides IA restructure (stack: #671 → #672 → #673 → #674). Adds the Overview section and completes the new sidebar.

• Introduction: rewritten around what KERNEL provides, why each browser runs in its own VM, and the open source projects behind it, ending with cards for See all features, Quickstart, and Cookbooks.
• See all features (new): a short answer, then the features grouped by job: running browsers, getting through real websites, carrying state, logins, and payments, and seeing what happened.
• Important concepts (new), titled "How KERNEL fits between your agent and the internet": the agent framework (model, system prompt, tools, skills, browser automation framework), browser infrastructure, and the internet, with a diagram, a "which piece to change" table, and where KERNEL fits in the agent stack.
• Why KERNEL? (new): how KERNEL works underneath your agent framework, then speed with the benchmark scope stated, what sets KERNEL apart, the problems you'd solve running Chrome yourself, and when an API or MCP is the better tool.

After this layer, the old sidebar groups are gone and the Guides sidebar is Overview, Start building, How it works, Partnering with KERNEL.

Testing

• mint validate and mint broken-links pass on this branch.
• The concepts diagram was rendered and checked in a local build.

Overview
Restructures the Guides sidebar by adding an Overview section and retiring the old Info group from primary navigation.

Introduction (index.mdx) is rewritten around KERNEL as an “internet runtime for agents,” unikernel rationale, open-source repos, and a slimmer get started card row (features, quickstart, cookbooks). The on-page fast setup copy-prompt block, prod setup, and scaling sections are removed (anchor spans remain for deep links).

New overview pages: See all features (feature catalog by job), Important concepts (agent framework vs browser infrastructure vs the internet, with agent-stack.svg and troubleshooting tables), and Why KERNEL? (positioning, benchmarks, DIY Chrome comparison).

Navigation & redirects: docs.json lists the three new pages under Overview and adds /overview/products → /overview/features. Integrations overview gets a one-line tie-in to concepts.

New SVG assets support the intro cards and concepts diagram.

Stale Bugbot comment from a previous run.

Left a few update suggestions, but overall, LGTM - i may have some final points at the end about highlighting browser repl more, but i want to read the other PRs and get them approved first potentially.

i ran these pages through Gauge's GEO / clarity checker!
