fix: replace CARemoteLayerServer with CAContext+CALayerHost for cross-process GUI

fix: wire onGuiCreated callback in HelperIPC constructor to send gui_ready notification

fix: call onGuiCreated callback after CARemoteLayerServer setup completes in showGui()

fix: send gui_ready notification after showGui — use callback from HelperPluginHost to IPC

fix: use setLayerPortName() instead of direct member access

fix: add setLayerPortName() public method (layerPortName is private)

remove old files replaced by .mm versions + Blocklist (now in PluginBridgeProcessor.h)

fix: restore setAlwaysOnTop(true) — fixes GUI opening in separate space in fullscreen

revert main.cpp — remove NSApplicationActivationPolicyAccessory (this broke the fullscreen behavior)

STOP — revert HelperPluginHost to last known working state (GUI in Helper but with original window behavior before all my 'fixes')

fix: show plugin GUI in-process (inside Ableton window) not from Helper

fix: set fullscreen-compatible behavior BEFORE making window visible

fix: GUI now floats over Ableton in fullscreen mode

fix: set NSApplicationActivationPolicyAccessory at launch to prevent separate app appearance

Fix GUI focus: Remove makeAccessoryProcess entirely, use NSWindow level trick to float without activation

Fix: Use Accessory activation policy — GUI shows without stealing focus from Ableton

Fix GUI close: Use JUCE custom title bar (not native) + force app activation via ObjC runtime

Fix: Make helper foreground process when showing GUI so window buttons work on macOS

Fix: Plugin GUI X button now closes window — custom DocumentWindow with closeButtonPressed override

Fix: Replace removed juce::Thread::setCurrentThreadPriority with native pthread priority (macOS)

Fix: HelperPluginHost.h use flat include for SharedAudioBuffer.h

Fix: HelperPluginHost.cpp use flat include for Constants.h

Fix: Helper/main.cpp use flat includes (Source/Shared in include dirs)

Fix: Remove MSG_NOSIGNAL from HelperIPC.cpp, fix include paths for macOS
