Axon v0.2.0

What's Changed

🚀 New Features

• TurboQuantDB as default vector store — tqdb (4-bit quantised, fast ANN) is now the default provider, replacing LanceDB. Storage path unified to vector_store_data/ (provider-agnostic). Install: pip install axon-rag (tqdb is a core dependency).
• Redesigned landing page — sticky navbar, hero CTA buttons (pip install axon-rag → PyPI, View on GitHub), real install + ingest + query terminal demo, Ollama local-first note with cloud fallback options.
• MCP protocol fix — notifications/initialized message now sent between initialize and tools/list per MCP spec; fixes agent-mode tool discovery in strict MCP clients.

🐛 Bug Fixes

• 414 MB wheels — src/axon/target/ (4 766 Rust build artefacts) was tracked in git and bundled by maturin. Untracked and added to .gitignore; wheels now ~5 MB.
• PyPI sdist rejection — LICENSE was missing from the sdist (License-File LICENSE does not exist in distribution file). Added explicit license-files and maturin sdist include.
• Broken PyPI images — PyPI cannot resolve relative image paths; dedicated PYPI_README.md with absolute raw.githubusercontent.com URLs used as the PyPI description.
• Release notes dumping full history — custom git log changelog script misattributed authors and dumped all commits on first tag. Replaced with generate_notes: true in release.yml.

🏗️ CI & Packaging

• Dropped deprecated macos-13 Intel runner (queued indefinitely on GHA); Intel Mac users install via sdist.
• Removed stale tmp_* build artefacts and old axon-copilot-0.9.0.vsix / vendor wheel binaries accidentally committed.
• pyproject.toml: URLs updated, tqdb>=0.2.1 promoted to core dependency.
