Improve error handling in forced shutdown path

[Copilot]

Addresses review feedback on PR #7528 regarding an empty catch block that silently swallowed exceptions during forced shutdown.

Changes:

• Added Console.Error logging for exceptions during ReleaseBloomToken() in the forced shutdown timeout handler
• Preserves non-blocking behavior while providing diagnostics if token release fails

catch (Exception ex)
{
    // If we can't log it, at least write to Console.Error.
    Console.Error.WriteLine($"Exception during ReleaseBloomToken: {ex}");
}

This improves debuggability when the 20-second shutdown timeout triggers and force-cleanup fails.
