Sync logs

[David2XN]

This changes logging execution from a global behavior in LoggerManager to a per-logger behavior.

LoggerManager now sends synchronous loggers immediately on the caller thread and dispatches only asynchronous loggers onto its serial background queue. FileLogger is configured as asynchronous, while the rest
of the built-in loggers remain synchronous by default. This makes console/native logs visible immediately during debugging or before crashes, without forcing file writes onto the caller thread.

What changed

• Added isAsynchronous: Bool to Logging, defaulting to false
• Updated LoggerManager to split log delivery into sync and async paths
• Kept FileLogger asynchronous
• Left other built-in loggers synchronous by default
• Fixed the Swift 6 retroactive conformance warning by marking OSLogEntry’s Identifiable conformance as @retroactive

Why

Previously, all loggers were funneled through the same async queue, which delayed console output. That made debugging worse because logs could be missing when hitting breakpoints or when the app crashed. With
this change, console-oriented loggers can remain synchronous, while heavier loggers like FileLogger can still run asynchronously.
