#===============================================================================
# Top-level app.asar patch orchestration: extract, wrap entry point, stub
# native module, copy i18n and tray icons, then invoke per-feature patches.
#
# Sourced by: build.sh
# Sourced globals:
#   claude_extract_dir, app_staging_dir, asar_exec, source_dir
# Modifies globals: (none directly — delegated patches may mutate electron_var)
