Reverts the cloning design from #3525 (useAgent per-thread clones, getThreadClone,
globalThreadCloneMap, cloneForThread) and #3630 (clone routing in activity renderers),
plus the inspector machinery that existed only to handle clones (onAgentRunStarted
subscriber + run-handler emissions from #3869, the connect-time emission from #3872,
and the agentRunThreadId map that read from it).
State-manager isClone composite-key path and SuggestionEngine consumerAgent param —
both added in #3525 to keep clones visible to bookkeeping — are gone too.
Restores agent.threadId = resolvedThreadId in CopilotChat (pre-#3525 behavior) and
swaps the inspector's agentRunThreadId map for a direct agent.threadId read.
Removes the DemoButtonAgent and /a2ui-demo page from the demo (added by #3630 as a
clone-fix repro).
Re-opens the original issue #2957 (CPK-7155): two CopilotChat instances with the same
agentId and different threadIds will share message state again. The follow-up is a
public registerProxiedAgent API so callers can opt into multiple frontend agents
proxying to the same runtime agent, without implicit per-thread cloning.
Adds a minimal demo at /a2ui-demo that uses the demo-button agent to
reproduce and validate the A2UI thread-clone bug fix. The agent renders
an A2UI surface with a Confirm button on first run; clicking it fires a
second run that emits a text confirmation message.

Incorporates the V1/V2 flat package consolidation (96885b595). All our
thread-isolation changes auto-merged to the new package paths. Three
content conflicts resolved (import paths updated from @/ aliases to
relative paths and @copilotkitnext/* to @copilotkit/*):
- packages/react-core/src/v2/hooks/use-agent.tsx
- packages/react-core/src/v2/hooks/use-render-custom-messages.tsx
- packages/react-core/src/v2/components/chat/CopilotChatMessageView.tsx
File location conflict resolved: use-agent-thread-isolation.test.tsx
moved from packages/v2/react/... to packages/react-core/src/v2/...
With per-thread agent clones, the registry agent has empty messages.
reloadSuggestions was checking messageCount on the registry agent, so
dynamic suggestions (which require messageCount > 0) never fired after
the first message. Fix by passing the thread clone (with actual messages)
through reloadSuggestions → generateSuggestions.
Also updates the demo to use claude-3-7-sonnet (extended thinking support)
when ANTHROPIC_API_KEY is set.

Flatten all packages from packages/v1/* and packages/v2/* into packages/* —
every package now lives directly under the @copilotkit/ scope with no v1/v2
subdirectories.
- Move all v1 packages (react-core, react-ui, runtime, shared, etc.) from
packages/v1/* to packages/*
- Absorb v2 react code into packages/react-core/src/v2/ (exported via /v2 subpath)
- Absorb v2 agent code into packages/runtime/src/agent/ (exported via /v2 subpath)
- Move v2 packages (core, angular, demo-agents, etc.) to packages/*
- Replace all @copilotkitnext/* imports with @copilotkit/* equivalents
- Keep @copilotkitnext/angular as the sole exception (angular remains on next)
- Update CI workflows, renovate config, release scripts for flat structure
- No public API surface changes — all exports fields are preserved
