v0.4.0 — Bundled 3D explorer + chatbot

code-graph-indexer is now self-sufficient: a fresh npm install (or npx) gives you the full 3D web explorer + chatbot — no monorepo clone required.

npx code-graph-indexer ui --root .

Packaging

• The 3D explorer + chatbot ship inside the package (dist/web); serve/ui serve them same-origin.
• New friendly ui command and an open_explorer MCP tool (14 tools total) so an agent can open the explorer and hand back a URL.
• Chatbot auth cascade: local claude CLI → ANTHROPIC_API_KEY env → in-UI key field → heuristic fallback.
• Friendly errors for a bad --root, missing tsconfig, and port-in-use.

Explorer UI

• Lands straight in your repo (no showcase picker for single-repo use).
• Orbit camera + damping replaces the jittery trackball; hover tracing is suppressed during a drag (no more mid-drag stutter).
• Framing fills the canvas; steel-cyan/teal file + folder colors instead of grey.

Docs

• Both READMEs rewritten in a human tone, leading with the ui command, plus faster/cheaper/reliable token+time estimate tables.

Verification: build ✓ · typecheck ✓ · lint ✓ · test ✓; fresh-install of the tarball boots and serves the UI + API end-to-end.
