Restructure modules: conductor-client-ai[-spring] rename, agent-examples/e2e rename, drop shim modules

[manan164]

Summary

• Renames the agent SDK modules conductor-ai → conductor-client-ai and conductor-ai-spring → conductor-client-ai-spring (via git mv, history preserved); published coordinates become org.conductoross:conductor-client-ai[-spring]
• Renames conductor-ai-examples → agent-examples and conductor-ai-e2e → e2e; neither applies maven-publish, so neither is ever published to Maven Central
• Removes the source-less publishing shim modules java-sdk (org.conductoross:java-sdk), orkes-client (io.orkes.conductor:orkes-conductor-client), and orkes-spring (io.orkes.conductor:orkes-conductor-client-spring) — consumers should depend on conductor-client / conductor-client-spring directly (CHANGELOG entry added)
• The SDK guides that lived in java-sdk/ (worker_sdk.md, workflow_sdk.md, testing_framework.md) move to docs/; README links updated
• harness drops its redundant :orkes-client dependency (the shim only re-exported :conductor-client, which harness already depends on)
• Docs, README, unreleased CHANGELOG entries, and the agent-e2e workflow updated to the new names; java package org.conductoross.conductor.ai[.spring] unchanged

Test plan

• ./gradlew :conductor-client-ai:compileJava :conductor-client-ai-spring:compileJava :agent-examples:compileJava :e2e:compileTestJava :harness:compileJava passes
• ./gradlew projects shows the expected module set
• git grep finds no stale references to any old module name
