📝 Walkthrough

Walkthrough

This PR removes the instance-scope tracking and blanket cleanup mechanism from Vue's SSR system, replacing it with targeted watcher handle cleanup. It reverts the __instanceScopes property, eliminates the exported cleanupContext() function, and updates tests to reflect the new behavior where watcher handles are cleaned up explicitly rather than via scope disposal.

Changes

Cohort / File(s) Summary
Test Updates
packages/server-renderer/__tests__/render.spec.ts		 Removed three SSR test cases verifying onScopeDispose cleanup and related effect-scope behavior, along with associated imports.
Test Assertions
packages/server-renderer/__tests__/ssrWatch.spec.ts		 Updated test assertions to expect ctx.__watcherHandles!.length to be 1 instead of 0 for watch and watchEffect with flush: 'sync' scenarios.
Type and API Removal
packages/server-renderer/src/render.ts		 Removed __instanceScopes property from SSRContext type, eliminated instance scope registration logic in renderComponentVNode, and deleted the exported cleanupContext() function entirely.
Cleanup Refactoring
packages/server-renderer/src/renderToStream.ts, packages/server-renderer/src/renderToString.ts		 Removed cleanupContext imports and replaced blanket scope cleanup with explicit iteration and unwatching of context.__watcherHandles handles after rendering completes.

Poem

🐰 A scope cleanup tale so fine,
Instance tracking? Not this time!
Watchers tidied, SSR bright,
No dispose calls in the night, 🌙
Server-side now serves just right!
