Remove the temporary diagnostics added during the iOS share-target
investigation, tagged with the TEMPORARY SHARE TARGET DIAGNOSTICS marker.
- Drop the pendingShareExists field/computation from ShareExtensionDiagnostics
across the Swift utility, TS definitions, and web stub
- Remove the cold-start diagnostics block in main.capacitor.ts (the iOS
getShareExtensionDiagnostics call and [ShareTarget] Cold-start state dump)
- Drop pendingShareExists from the getShareExtensionDiagnostics log line
Kept getShareExtensionDiagnostics itself (unmarked plugin API + registration),
the unmarked [ShareTarget] print logging, share-target functionality, and
Android code unchanged.
