## What changed?
- Ensure the TQs receive and apply the right version data after revive.
- Made delete propagation to always happen serial to other propagations.
It ensures all other propagations are cancelled before starting delete
propagation.
- Deprecate the `deleted` flag in version data and the GC logic around
it. Now we use the good old forgetVersion path which immediately removes
the version data from TQ.
- Ensure version state is reset after revive, in case the recreation
happened before workflow close.
- Also, now workflows CaN based on SDK suggestion if no pending Signal
or Update is present.
## Why?
The version could stuck at deleted state from TQ POV if revived before
the (now deprecated) GC logic cleans it up.
