Serve the TypeScript-style MCP docs page on Python GET /.

[abhijitt-code]

Summary

• Replace the Python stub landing page with the TypeScript documentation page (connection setup + tool catalog).
• Vendor this SDK via [tool.uv.sources] so NitroCloud uv sync and Open URL use the new page without an invalid file: Requires-Dist.
• Ignore vendor/ and stop tracking bytecode.

Test plan

• GET / on python-starter, python-pizzaz, and python-oauth shows Connection Setup and tools
• NitroCloud Python uv build succeeds (no file: wheel metadata error)
• Open URL after deploy shows the new page, not "This is not a website"

Verdict: request changes

GET / matches the TypeScript docs page. I booted it locally: Connection Setup, tool catalog (echo, search_records), not the old stub. Landing tests passed; CI is green.

Blocker: nitrostack-py install vendors the SDK and rewrites requirements.txt to ./vendor/nitrostack, which skips uv sync. Vendor on init/pack only, and keep the dep name as nitrostack so uv still resolves via [tool.uv.sources]. Also drop the hardcoded 0.3.2 fallback.

Local GET / on this branch. This is the TypeScript-style docs page (Connection Setup + tools), not the old stub.
