## Summary
Rewrites the stale root `README.md` against the current docs (structure
modeled on [earendil-works/pi](https://github.com/earendil-works/pi)'s
README).
- **Quickstarts** now use the session-based API (`composio.create()` →
`session.tools()`) that the docs treat as canonical, replacing the
legacy `composio.tools.get()` flow
- **Positioning** matches the docs welcome page: 1000+ pre-authenticated
toolkits, per-user sessions, auth, triggers, and a sandbox
- **New sections**: CLI install (curl / Homebrew / npm),
sessions-via-MCP note, repository layout, minimum runtime versions
- **Provider table** merged with package links; adds the Claude Agent
SDK providers (both SDKs) and the experimental Pi provider
(`@composio/experimental`); documents the Python
`composio-gemini`/`composio-google`/`composio-google-adk` split
- **Removed**: Rube section (no longer in docs), cover banner (replaced
with theme-adaptive brand logomark from brand.composio.dev),
master-branch pointer, internal OpenAPI-pull section, private
`@composio/ts-builders` listing
Docs-only change — no changeset needed.
