docs: refresh homepage and prune navigation

[jayhack]

Summary

Refreshes the marketing homepage and trims the docs navigation down to what we still support.

Homepage (site/app/page.tsx)

Above the fold now emphasizes:

• A fast, in-memory codebase index that captures more than the AST (imports, exports, usages, references).
• Backed by tree-sitter (with heavy indexes moving into Rust for scale).
• Optimized for coding agents.
• An inline delete_dead_code.py example (loops codebase.functions, removes those with no usages, then commit()).
• The uvx graph-sitter command pattern (parse, then transform … --check/--write).

The explicit graph visualization was dropped in favor of the dead-code script. The existing Explore nav link is preserved. Below the fold: three use cases (large-scale reorganization, dead-code monitoring & deletion, codebase visualization) and the uvx graph-sitter command surface.

Navigation cleanup

• Tutorials removed: MCP Server, Documentation, Code Research Agent, Neo4j Graph.
• Introduction removed: Advanced Settings, Community, IDE Usage, AI Integration; also dropped LLM Integration (building-with-graph-sitter/calling-out-to-llms).
• Broken sections removed: use-cases, organizations, users (and pruned from the section order in site/lib/docs.ts).
• Installation rewritten to focus on uvx.
• Overview pinned to the top of Introduction via a new sidebarOrder frontmatter field (supported in site/lib/docs.ts).
• Fixed the resulting dead links across remaining intro/building-with/tutorial pages.

Note

A duplicate docs/graph-sitter/ section (mirrors Introduction) still links to some removed pages; left untouched as it's out of scope for this pass.

Test plan

• npm run build in site/ passes (TypeScript checks + 287 static pages, incl. / and /explore).
• Visual review of the homepage above the fold.
• Spot-check the Introduction sidebar (Overview first) and confirm removed sections are gone.
