build: migrate groupId to io.agentruntimecontrolprotocol; fix repo URLs

Switch published Maven coordinate from dev.arcp:* to
io.agentruntimecontrolprotocol:*; namespace is verifiable on Sonatype
Central via DNS TXT on agentruntimecontrolprotocol.io, whereas dev.arcp
required owning the arcp.dev domain. Fix POM url/scm metadata to point
at agentruntimecontrolprotocol/java-sdk instead of nficano/arpc.

Java package names (dev.arcp.*) unchanged — groupId and package are
independent in Maven.

-`dev.arcp:arcp` is the Java reference implementation of [ARCP](https://github.com/agentruntimecontrolprotocol/spec/blob/main/docs/draft-arcp-1.1.md), the Agent Runtime Control Protocol. It covers both sides of the wire — `arcp-client` for submitting and observing jobs, `arcp-runtime` for hosting agents (with `arcp-runtime-jetty` for networked WebSocket runtimes) — so either side can talk to any conformant peer in any language without hand-rolling the envelope, sequencing, or lease enforcement.

 ARCP itself is a transport-agnostic wire protocol for long-running AI agent jobs. It owns the parts of agent infrastructure that don't change between products — sessions, durable event streams, capability leases, budgets, resume — and stays out of the parts that do. ARCP wraps the agent function; it does not define how agents are built, how tools are exposed (that's MCP), or how telemetry is exported (that's OpenTelemetry).
 
 ## Installation
 
-Requires JDK 21 LTS. Artifacts are published to Maven Central as `dev.arcp:*`; the `arcp` umbrella re-exports `arcp-client` and `arcp-runtime`. Pull just the side you need à la carte, or pick up framework middleware (`arcp-middleware-spring-boot`, `-jakarta`, `-vertx`), the OpenTelemetry adapter (`arcp-otel`), and the Jetty WebSocket runtime (`arcp-runtime-jetty`) as needed:
