fix(catalog-backend): remove immediate mode stitching

Browse Source 
Remove the immediate stitching strategy from the catalog-backend plugin.
All stitching now uses the deferred mode exclusively, which processes
entities asynchronously via a worker queue. This simplifies the stitching
subsystem by removing dead-weight code paths and the strategy parameter
threading, and fixes a bug where deleteWithEagerPruningOfChildren
hardcoded immediate-mode semantics regardless of configured mode.

'@backstage/plugin-catalog-backend': patch
---
Removed the immediate mode stitching strategy. All stitching now uses the deferred mode, which processes entities asynchronously via a worker queue. If your configuration includes `catalog.stitchingStrategy.mode: 'immediate'`, it will be ignored with a deprecation warning. The `pollingInterval` and `stitchTimeout` settings continue to work as before.
