docs(plugin): wire SceneView Claude Code plugin into core install surfaces

Drive plugin discovery from every doc surface where users learn how to
connect SceneView to an AI assistant:

- llms.txt: new 'Claude Code plugin (one-command install)' subsection
  under '## AI Integration', explains the plugin bundle (MCP + 11
  namespaced commands + hooks) right next to the bare-MCP snippet
- docs/docs/ai-development.md: 'Use with Claude Code' section now
  presents the plugin as the recommended path with the bare MCP as the
  fallback. Slash-command table mentions the /sceneview: prefix and
  flags the /review /test built-in collision per the multi-agent review
- docs/docs/index.md: extra 'Claude Code Plugin' button next to the
  existing 'MCP Server on npm' / Discord / GitHub buttons in the
  community CTA block
- mcp/README.md (sceneview-mcp npm package): the 'Claude Code' install
  block now leads with the plugin install (recommended) and keeps the
  bare-MCP option as the lighter fallback

Plus: GitHub topics added to sceneview/claude-marketplace
(claude-code, claude-plugin, mcp, 3d, ar, android, ios, web,
jetpack-compose, swiftui, sceneview) for marketplace + topic-search
discoverability.

+Inside the SceneView repo with Claude Code (commands shown unprefixed work locally; once you install the [SceneView plugin](https://github.com/sceneview/claude-marketplace), they're available everywhere as `/sceneview:*`):
 
 | Command | What it does |
 |---|---|
 | `/contribute` | Full guided workflow — understand the codebase, make changes, prepare a PR |
 | `/review` | Check threading rules, Compose API patterns, Kotlin style, module boundaries |
 | `/document` | Generate/update KDoc for changed public APIs, update `llms.txt` |
 | `/test` | Audit test coverage and generate missing tests |
+| `/release`, `/quality-gate`, `/publish-check`, `/sync-check`, `/version-bump`, `/evaluate`, `/maintain` | Pre-PR + release lifecycle |
+
+> **Tip — namespace conflict:** the bare `/review` and `/test` commands shadow Claude Code built-ins. With the plugin installed, prefer the prefixed forms `/sceneview:review` and `/sceneview:test` to disambiguate.
