## Summary
- `@copilotkit/runtime-client-gql` declared `@copilotkit/runtime` as a
dependency, but never imports from it at runtime
- This caused barrel re-exports to pull server-side code into client
bundles (600KB → 4.3MB)
- Removed the package.json dependency and added an Nx
`implicitDependencies` entry to preserve build ordering (graphql-codegen
needs the schema file that runtime generates)
Fixes#3225
## Test plan
- [x] Verified no source imports from `@copilotkit/runtime` in
runtime-client-gql
- [x] Nx build ordering preserved via `implicitDependencies`
- [x] Full build passes (including graphql-codegen)
- [x] All tests pass

## Summary
- The A2UI Composer's Image component used `via.placeholder.com` URLs
for fallback/placeholder images
- That domain is dead, resulting in broken images
- Replaced with `placehold.co` which provides the same service
Fixes#3109
## Test plan
- [x] Verified no remaining references to `placeholder.com` in the
codebase
- [x] Build passes

## Summary
- v2 CopilotChat components were missing the CSS class names that v1
provided (`copilotKitMessages`, `copilotKitInput`,
`copilotKitResponseButton`, etc.)
- Users relying on these classes for custom styling had no way to target
v2 components
- Added matching CSS classes to all relevant v2 chat components
Fixes#3133
## Test plan
- [x] Test verifying all expected CSS classes are present on rendered
components
- [x] Full package test suite passes
- [x] Build passes

Investing a lot of time and effort just to find out it doesn't align
with the upstream project feels awful, and we don't want that to happen.
It also helps to make sure the work you're planning isn't already in
progress.

## What does this PR do?
This PR adds an initial scaffolding of the CopilotKit Intelligence agent
runner and React agent classes.
Both will be part of the new threads-enabled feature set, and will be
iterated upon in subsequent PRs.
For this PR, the React agent is not tied into `useAgent`, so it cannot
currently be interacted with.
Also, in this PR, docs that describe the agent and runner architecture
are not updated, as it is assumed that these classes may change
substantially and rapidly in the very near term.
A big part of this PR is the integration of the Phoenix JS client SDK to
enable the IntelligenceAgent and IntelligenceAgentRunner to connect to
the Intelligence platform's Phoenix server. That allows threaded AG-UI
messages to be streamed from to and from the platform, instead of
directly from agent runner to client agent hook.
The message structure for the Phoenix connection is still in flux.
Note: while the SQLite-backed agent runner is in a separate package, the
IntelligenceAgentRunner was intentionally placed along side the
`ProxiedCopilotRuntimeAgent` to make it that much easier to switch from
the latter to the former if desired.

## Checklist
- [x] I have read the [Contribution
Guide](https://github.com/copilotkit/copilotkit/blob/master/CONTRIBUTING.md)
- [ ] If the PR changes or adds functionality, I have updated the
relevant documentation
## Summary
- During streaming, `AbstractAgent.addMessage()` can push messages with
the same `id` into the messages array, causing React duplicate key
warnings in `CopilotChatMessageView`
- Added Map-based deduplication in the message rendering pipeline —
last-write-wins for duplicate IDs
- Includes dev-mode `console.warn` when duplicates are detected, to
surface the upstream cause without breaking the UI
Fixes#3258
## Test plan
- [x] Unit tests added verifying deduplication behavior
- [x] Warning logged in development when duplicates detected
- [x] Full package test suite passes
- [x] Build passes

Reverts the resolveAgent extraction from the previous commit — the
original useMemo + ref cache already provides referential stability.
All 4 stability tests pass without the refactor.
runtime-client-gql's graphql-codegen needs the schema file generated
by @copilotkit/runtime's build. After removing the package.json
dependency (to fix bundle size), Nx no longer orders the builds
correctly. implicitDependencies restores build ordering without
reintroducing the runtime dependency.
The @copilotkit/runtime-client-gql package listed @copilotkit/runtime as
a dependency, but none of its source files actually import from it. This
caused the entire server-side runtime (graphql-yoga, hono, openai, shiki,
reflect-metadata, etc.) to be pulled into client bundles, exploding
bundle size from ~600kb to 4.3mb+.
Remove the unused dependency from package.json, the UMD externals list,
and the UMD globals map in tsdown.config.ts.
