Remove all empty "Under Construction" placeholder pages for server/
and client/ directories. Only pages with actual content should exist.
- Remove docs/server/ and docs/client/ placeholder pages
- Strip mkdocs.yml nav to only pages with real content
- Remove broken links from concepts.md and quickstart.md (replaced
with TODO comments for when those pages are created)
- Simplify index.md by removing card grid linking to non-existent pages
Set up the foundation for migrating documentation from README.v2.md
into proper docs pages served by mkdocs.
- Rewrite `docs/index.md` as a concise landing page with card grid
- Add `docs/quickstart.md` with a complete getting-started guide
- Fill `docs/concepts.md` with protocol architecture, primitives,
transports, context, and lifecycle overview
- Restructure `mkdocs.yml` nav into Server, Client, and top-level
sections
- Create `docs/server/` and `docs/client/` directories with
placeholder pages for upcoming content
- Move `docs/low-level-server.md` to `docs/server/low-level.md`
