## Summary by cubic
Adopted the new typed IPC contracts across the app, replacing IpcClient
with namespaced ipc methods. Restored app output streaming via events,
added maxOutputTokens for custom model flows, migrated custom theme
operations to ipc.template, and fixed chat stream cancellation
lifecycle.

- **Refactors**
- Replaced IpcClient usage with ipc.* namespaces (system, app, chat,
github, git, version, languageModel, neon, visualEditing, context,
prompt, mcp, misc, capacitor, template, events, upgrade, agent,
proposal).
- Moved type imports from "@/ipc/ipc_types" to "@/ipc/types"; adjusted
renamed types and paths (e.g., ListedApp under "@/ipc/types/app",
security types under "@/ipc/types/security").
- Updated method signatures to use object params and new return shapes
(e.g., getAppVersion returns { version }).
- Subscribed to ipc.events.misc.onAppOutput in useRunApp to process app
output, restore preview URL updates, and handle HMR after API changes.
- Added missing maxOutputTokens in create/edit custom model dialogs;
small UI and hooks changes to align with new contracts.
- Fixed DeepLinkData typing by re-exporting a discriminated union for
correct type narrowing.
- Migrated custom themes and theme generation to ipc.template.*; added
CustomTheme and theme generation types.
- Moved methods to correct namespaces (e.g., takeScreenshot/restartDyad
→ system; checkProblems → misc).
- Emit chat:stream:end on stream cancellation for consistent renderer
cleanup.

- **Migration**
  - Replace any remaining IpcClient references with ipc.*.
- Update type imports to "@/ipc/types" and adjust for changed/optional
fields (e.g., App lists use ListedApp; Collaborator.permissions and
VercelProject.framework may be optional).
- Verify callers for new parameter objects and result shapes; replace
runApp/restartApp callbacks with ipc.events.misc.onAppOutput
subscriptions.
