Fixed

• PVLogging double OSLog emission — DLOG/ILOG/etc. previously emitted two OSLog entries; now only one per call.
• DLOG log level bug — DLOG was publishing at .verbose severity instead of .debug in PVLogPublisher.
• WLOG double-emoji — WLOG prepended ⚠️ before passing to log() which also adds an emoji.

Changed

• PVLogging OSLog subsystem — replaced Bundle.main.bundleIdentifier with static "com.provenance-emu.provenance", correct in unit tests and extension targets.
• PVLogging uses #fileID — replaces #file (full path) with Module/Filename.swift format to avoid leaking build-machine paths into logs.

Added

• PVLogging new categories — .emulator, .ui, .controller, .saveState, .library for finer-grained Console.app filtering.
• PVLogPublisher AsyncStream — makeLogStream() -> AsyncStream<LogEntry> for Swift 6 structured-concurrency log consumers.
• Per-category log level filtering — PVLogPublisher.setMinLevel(_:forCategory:) suppresses noisy categories at runtime.
• os_signpost helpers — new PVSignpost.swift with withSignpost(), signpostBegin/End(), and signpostEvent() for Instruments frame/audio profiling.
