docs: update README badges and install section for new package name

PyPI shield and Python-versions shield now point at
`agentruntimecontrolprotocol`. Install section documents the new name
and the per-extras layout (`[runtime]`, `[otel]`, `[jwks]`, `[all]`,
`[test]`) instead of the old single-install line.

 ## Installation
 
-Requires Python 3.11 or later. The SDK ships as a single wheel containing the client, runtime, transports, ASGI/aiohttp middleware, the OpenTelemetry middleware, and the `arcp` CLI. Install from PyPI with `pip`, `uv`, or any PEP 517 resolver; the optional `jwks` extra pulls in `httpx` for remote JWKS verification.
+Requires Python 3.11 or later. The package is published on PyPI as `agentruntimecontrolprotocol`; the import name stays `arcp`. The default install gives you the client, transports, and CLI out of the box — heavier server-side deps live behind extras so client-only users don't pull them in.
 
 ```sh
-pip install arcp
-# or, with uv:
-uv add arcp
-# with the JWKS extra:
-pip install "arcp[jwks]"
+# client side — submit and observe jobs
+pip install agentruntimecontrolprotocol
+
+# runtime side — accept jobs, verify JWTs, persist event logs to sqlite
+pip install "agentruntimecontrolprotocol[runtime]"
+
+# everything (runtime + otel + jwks)
+pip install "agentruntimecontrolprotocol[all]"
 ```
 
+Other extras: `[otel]` for OpenTelemetry middleware, `[jwks]` for remote JWKS verification via `httpx`, `[test]` for the pytest stack used by the suite.

 ## Quick start
 
 Connect to a runtime, submit a job, stream its events to completion:
