- Kill useJsonStable in CopilotChatConfigurationProvider — useShallowStableRef
is now the single stabilization primitive for both messageView props and labels
- Harden useShallowStableRef with isPlainObject guard so arrays, Dates, and
class instances are never shallow-compared (reference-only for non-plain objects)
- Remove redundant stableParentLabels — parentConfig?.labels is already stabilized
by the parent provider's own useShallowStableRef
- Uninstall ts-deepmerge from react-core dependencies (no longer imported anywhere)
- Add unit tests for useShallowStableRef in slots.test.ts (5 tests)
- Add changeset (patch) describing the FOR-75 performance fix

- Add package.json exports for v2/{express,hono,node} subpaths
- Add elysia devDependency and tsdown entry points
- Exclude bun integration tests from vitest config
- Update CI workflows to include runtime-servers test job
- Add runtime-server-adapter docs page
- Add changeset for the fetch-based runtime feature
The @copilotkit/eslint-config and eslint-config-custom packages were
removed from the workspace but still referenced in changeset files,
causing `changeset version` to fail during release CI.
- Remove @copilotkit/eslint-config from consolidate-v1-v2-packages changeset
- Remove @copilotkit/eslint-config and eslint-config-custom from pre.json initialVersions
- Remove dead eslint-config-custom link from cursor rules

The previous publish workflow released 1.55.0-next.8 to npm but the
post-release commit failed to push to main (blocked by branch
protection). This applies the version bumps and pre.json updates that
the workflow would have committed, unblocking future releases.

- Add cardinality assertions (toHaveLength(1)) to all 5 auto-close tests
so duplicate REASONING_MESSAGE_END / REASONING_END events are caught
- Add missing RUN_FINISHED final-event assertion to abort auto-close test
- Add test for consecutive reasoning blocks with no reasoning-end between
them (exercises closeReasoningIfOpen inside reasoning-start)
- Add test for exception thrown mid-stream (exercises catch block path)
- Add test for stream exhaustion without terminal event while reasoning is
open (exercises !terminalEventEmitted fallback)
- Expand changeset description to cover all three behavioral fixes

Two fixes for Anthropic model stalls (fixes#3323):
1. Skip reasoning-delta events with empty text — EventSchemas.parse()
rejects delta: "" and kills the RxJS Observable before any other
events can fire.
2. Auto-close open reasoning lifecycle at every phase transition —
@ai-sdk/anthropic never emits reasoning-end, leaving the state
machine stuck.

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/...
After the V1/V2 consolidation merge, several changesets still referenced
old @copilotkitnext/* package names that no longer exist. Fixed package
references and ran changeset version to apply pending version bumps.

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

Multiple CopilotChat components with the same agentId but different
threadIds were sharing a single agent instance, causing message state
to bleed between them. The useAgent hook now creates per-thread clones
keyed by agentId:threadId, keeping messages and state isolated.
Closes#2957

## Summary
`<CopilotSidebar defaultOpen={false} />` was opening anyway because the
prop was not being forwarded through the provider chain. This PR fixes
that - and also addresses the architectural trade-off flagged in review.
### Who is affected
**User A** just uses `<CopilotSidebar />` with no outer provider
Before the fix, their sidebar opened by default. After the fix, it still
opens by default. Nothing changed for them.
**User B** uses `<CopilotSidebar defaultOpen={false} />`
Before: broken (opened anyway). After: works.
**User C** wraps their app in a bare `CopilotChatConfigurationProvider`
and reads `isModalOpen` from it.
Before our fix `isModalOpen` was stuck at true forever. After: it
reflects the sidebar's state.
### What changed
- The `defaultOpen` prop is forwarded correctly through the provider
chain to both `CopilotSidebar` and `CopilotPopup`.
- Outer `useCopilotChatConfiguration()` hooks now reflect sidebar state.
Fixed via bidirectional state sync between nested providers.
### Files changed
- `packages/v2/react/src/components/chat/CopilotChat.tsx` - accept and
forward `isModalDefaultOpen`
- `packages/v2/react/src/components/chat/CopilotSidebar.tsx` - pass
`isModalDefaultOpen={defaultOpen}`
- `packages/v2/react/src/components/chat/CopilotPopup.tsx` - same
- `packages/v2/react/src/providers/CopilotChatConfigurationProvider.tsx`
- fix resolution logic + bidirectional sync
-
`packages/v2/react/src/providers/__tests__/CopilotChatConfigurationProvider.test.tsx`
- add tests
### Test plan
- [x] 843 tests pass (including 4 new bidirectional sync tests)
- [x] New tests cover all three reproduction scenarios from
