refactor(workbench): move dev-server registration into workbench-cli

[gu-stav]

Description

Registration drives the registry, so it belongs beside it; the CLI now injects only what it owns — the resolved app id and the manifest extractor — keeping workbench-cli free of CLI config/manifest conventions.

What to review

The injected appId/extractManifest seam on startDevServerRegistration, and the deprecated-id check moving up to the caller.

Testing

Registration + manifest-watcher unit tests moved with the code; the deprecation tests are relocated to the devAction suite.

---

Note

Medium Risk
Touches workbench dev registration and manifest watching on the critical sanity dev path; behavior should be equivalent but wiring and test placement changed.

Overview
Moves startDevServerRegistration from @sanity/cli into @sanity/workbench-cli and re-exports it on @sanity/workbench-cli/dev, next to the dev-server registry.

devAction now calls that export and injects CLI-owned concerns: checkForDeprecatedAppId and getAppId run before registration, and an extractManifest callback picks studio vs core-app extraction (extractStudioManifest / extractCoreAppManifest). Workbench-cli no longer imports CLI manifest helpers or appId utilities.

Registration tests live in workbench-cli with a slimmer extractManifest / appId API; deprecated app.id vs deployment.appId coverage moves to the devAction unit suite. extractStudioManifest import paths are corrected under actions/manifest, and the manifest watcher uses local dev modules plus subdebug from cli-core instead of a CLI devDebug helper.
