ci: add dexdex iOS smoke build job (#304)

## Summary
- add a new `node-dexdex-ios-build` job to `.github/workflows/CI.yml`
- run unsigned DexDex iOS smoke build on `macos-latest` using:
  - `pnpm --filter dexdex exec tauri ios init --ci`
- `pnpm --filter dexdex exec tauri ios build --ci --debug --target
aarch64-sim`
- include the new job in `ci-result` aggregation
- sync CI contract docs in `AGENTS.md` and
`docs/apps-dexdex-desktop-app-foundation.md`

## Testing
- not run locally (workflow/docs only change)
