v0.2.0

Changed

• Replace AppleScript with ANSI escape sequences for all color operations
  • Eliminates cross-process Apple Events that caused Terminal.app heap corruption
  • Reduces color change latency from ~130ms to <1ms
  • No longer spawns osascript processes
• Session end and fade-out now reset to Terminal.app default color instead of
  saving/restoring exact original color (ANSI escape sequences cannot read
  current background color, but \033]6;1;bg;*;default\007 resets cleanly)
• Removed claude-semaphore-original temporary file (no longer needed)

Fixed

• Terminal.app crash — high-frequency AppleScript Apple Events caused heap
  corruption in Terminal.app's main thread, manifesting as 4 different crash
  types (SIGABRT/SIGSEGV/SIGBUS/SIGTRAP) over 5 days. Root cause: cross-process
  osascript calls forced Terminal to traverse ObjC window/tab objects on the
  main thread, racing with its own rendering and tty-io threads. Crash reports
  consistently showed memory corruption signatures (free_list_checksum_botch,
  objc_msgSend use-after-free, memmove bus error, CFGetTypeID invalid
  tagged pointer). Switching to in-process ANSI escape sequences eliminates
  all cross-process communication with Terminal.app.
