Pastefix v1.2.0

v1.2.0 unifies the entire cleaning pipeline into background AutoMonitor, removes the redundant Alt+V hotkey and keystroke simulation, and adds single-instance mutex protection.

What changed

1. Unified "Copy-to-Fix" Pipeline (Zero extra keystrokes)

• Previously, AutoMonitor only performed Dedent, while joining continuations required pressing Alt+V.
• In v1.2.0, the pipeline is fully unified: whenever you copy text, AutoMonitor automatically runs the complete normalization (Dedent + margin repair + continuation joining) within 300ms in the background.
• You can simply use standard Ctrl+V or mouse right-click to paste into WezTerm, Windows Terminal, or any application.

2. Removed Alt+V Hotkey & Window-Class Paste Simulation

• Eliminated global hotkey registration (WM_HOTKEY) and SendInput keystroke injection.
• No more hotkey collisions with other applications, no stuck modifier keys, and zero accidental keystroke side-effects.
• Simplified settings.json to a single toggle: AutoMonitor.

3. Single-Instance Mutex Protection

• Added a named system mutex (PasteFix_App_SingleInstance_Mutex) to prevent multiple background instances from running simultaneously and competing for clipboard events.

4. Reverse-Paste Root Cause & Resolution

• Investigated and resolved the multi-line reverse paste issue in PowerShell on Windows:
  • Cause: Setting canonicalize_pasted_newlines = "LineFeed" in terminal emulators (e.g. WezTerm) forces raw \n characters into the Windows ConPTY pipeline, causing PSReadLine asynchronous continuation parsers to process multi-line streams in reverse order.
  • Solution: Retain native Windows line breaks (CRLF / CR) to ensure strictly ordered, non-inverting execution.
