## Summary
This PR improves the workaround introduced in #33335 that handles cases
where the pinned tab count exceeds the actual tab count during workspace
deserialization.
## Problem
The original workaround in #33335 successfully prevented the panic but
had two issues:
1. **Console spam**: The warning message was logged repeatedly because
`self.pinned_tab_count` wasn't updated to match the actual tab count
2. **Auto-pinning behavior**: New tabs up until you exceed the old safe
tab count were automatically pinned after the workaround was triggered.
## Solution
Updates the defensive code to set `self.pinned_tab_count = tab_count`
when the mismatch is detected, ensuring:
- The warning is only logged once when encountered.
- New tabs behave normally (aren't auto-pinned)
- The workspace remains in a consistent state
This is an immediate fix for the workaround. I'll attempt to open up a
follow-up PR when i get the chance that will address the root cause by
implementing serialization for empty untitled tabs, as discussed in
#33342.
