Community docs fixes, checked against the self-hosted server source.
- CONTRIBUTING.md: setup steps and project structure match the repo (#1745).
- README: link the self-hosting quickstart (#1713).
- Self-hosting: database snapshot behavior (#1687) and embedding env vars, local model dimensions and the v0.0.6 upgrade lock (#1659), trimmed to what the code does.
- Docs sidebar: hover and selected state CSS from #1784, without the duplicated bold icon set.
- `SUPERMEMORY_DATA_DIR` now defaults to `~/.supermemory` (server-v0.0.9).
