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.

Attachment queue & previews:
- Image lightbox with View Transition API morph animation
- Video lightbox with native controls and play button overlay
- Document lightbox (PDF via blob URL, text inline, info card fallback)
- Drop zone overlay with upload icon
- Filename preservation via InputContent metadata
- Proper video thumbnail sizing and play/pause indicator
- Fix attachment queue positioning (max-w-3xl constraint)
- Padding between X button and content for audio/document cards
- Document filenames wrap instead of truncating
Attachments config:
- onUploadFailed callback for validation/upload errors (file-too-large, invalid-type, upload-failed)
- onUpload accepts sync or async returns
- AttachmentUploadResult discriminated union with explicit interfaces
- Metadata field on Attachment and onUpload return type
AG-UI version bump:
- Bump @ag-ui/client, @ag-ui/core, @ag-ui/encoder, @ag-ui/proto to 0.0.51
- Remove process.env Vite workaround (fixed upstream in 0.0.51)
Deprecation lifecycle:
- @deprecated JSDoc on all legacy image upload APIs
- ImageRenderer, ImageRendererProps, ImageUpload type, imageUploadsEnabled prop,
inputFileAccept prop, ImageRenderer prop, AIMessage.image, ImageData
- Codemod at codemods/migrate-attachments.ts (15 tests)
- Migration guide updated with codemod instructions and new type shapes
Docs:
- New guide: docs/(root)/multimodal-attachments.mdx
- Updated migration guide with onUpload return type, metadata, codemod section
- Cross-links from prebuilt-components and migration guide
- Label change: "Add photos or files" → "Add attachments"
Tests:
- CopilotChat.attachments.test.tsx — 5 tests for onUploadFailed
- migrate-attachments codemod — 15 tests
Replace eslint and prettier with oxlint and oxfmt for faster linting
and formatting across the monorepo. Remove all eslint and prettier
configs, dependencies, and related packages. Add .oxlintrc.json and
.oxfmtrc.json for the new tooling. Update CI workflows and lefthook
hooks accordingly. Reformat codebase with oxfmt.

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

Run prettier on ~1,865 files across examples/ to match the monorepo's
formatting standards. These files were imported as-is from standalone
repos that used different prettier configs.
