Code Review
This pull request refactors the subscription removal logic in event_store.go to use the slices.Delete function, which is a good improvement for code readability. However, the slices package is not imported in the file, which will cause a compilation error. This critical issue needs to be addressed.

Using slices.Delete improves readability, which is a good refactoring. However, the slices package is not imported in this file, which will cause a compilation error. Please add "slices" to the import block to resolve this.

- Line 1492: The code calls slices.Delete on tableState.Subscriptions (line
using slices.Delete) but the "slices" package is not imported; add the standard
library import "slices" to the import block so the call to slices.Delete
compiles, ensuring the import is placed with other stdlib imports and not in a
separate grouped import.

Missing slices import — this won't compile.
slices.Delete is used at line 1492 but the "slices" package is not imported. Add "slices" to the standard library import group:
import (

"strconv"
"sync"📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
