fix(server): reconcile active sessions after restart - #7463

💭 Good, the ProviderSessionDirectoryShape issue from the prior run is already fixed in the diff. Now I want to check the other changed files, particularly serverRuntimeStartup.ts and ProviderCommandReactor.ts, to verify the stalePendingRequestDetail helper and its imports are correctly set up. The imports look standard with namespace subpath imports. Now I want to check the new reconcileProviderSessions function and see where it's used. I'm checking whether catching the whole error channel here is appropriate since the binding effect's errors are fully handled, then looking at whether logging the raw error object alongside threadId stays within the bounds of safe, sanitized logging conventions. The dependency acquisition via yield* Service looks correct, and the test file's use of satisfies with Partial and "as never" matches what was already flagged as resolved. Now I want to verify the test file consolidates its imports from "effect" properly. The imports and test setup look fine, using named error imports and service injection appropriately. I'm checking whether ProviderSessionDirectory exports the expected types and whether this PR touches that module's shape definitions. Confirming the previously flagged issue is now resolved by checking the relevant lines, and both spots correctly use the Partial service type. The ProviderCommandReactor change is scoped to helper usage only, so nothing else stands out. I don't see any remaining violations, so this should resolve as a clean pass with no findings to report.
