#!/usr/bin/env bash
# Makes the built app fully self-contained so it runs by double-click without
# any MSYS2/Qt directory on PATH. Run from an MSYS2 UCRT64 shell after building:
#
#     ./deploy.sh                       # defaults to build/bin/SubtitleGeneratorAI.exe
#     ./deploy.sh path/to/App.exe
#
# Why this exists: on MinGW/UCRT, windeployqt copies the Qt DLLs + plugins but
# NOT the compiler runtime (libstdc++, libgcc, libwinpthread) or Qt's own
# third-party dependencies (zstd, pcre2, icu, harfbuzz, ...). Without those the
# exe silently loads whatever Qt6Core.dll it finds on PATH, which triggers the
# "entry point qResourceFeatureZstd could not be located" crash on mismatch.
