update doc type and make result_type camelcase resultType

Cross-referenced the open issues in experimental-ext-server-card so the
charter does not assert things the WG is still deciding:

- Reference Implementation: cite python-sdk#2696 (open, in review) as the
  in-progress SDK reference impl instead of claiming none exists (#16).
- Stop presenting .well-known as locked: add a discovery-mechanism open
  item for the .well-known-vs-GET-on-URL question (#12) and make the IANA
  registration conditional on that outcome.
- Align the path/media-type open items with the reference impl's slash-form
  vote (#11) and the application/mcp-server-card+json direction (#9).
- Add an auth-shape open item flagging the limited initial shape and the
  additive SEP-2742 auth fast-follow / forward-compat requirement (#13, #17).
- Note that whether to add primitive listings is itself open (#10).
