#!/usr/bin/env bash
# visionA Agent Linux AppImage builder
#
# 必須在 Linux x86_64 跑（GitHub Actions ubuntu-latest 即可）。
# 需要的工具：appimagetool、wails CLI、go 1.26+、pnpm、curl
#
# 前置：payload/linux/ 應已由 `make payload-linux` 產出，
#       visiona-agent/build/bin/visiona-agent（Wails app binary）應已由 `make wails-linux` 產出。
#
# 用法：
#   VERSION=0.1.0 bash installer/linux/build-appimage.sh
#
# 產物：dist/visiona-agent-${VERSION}-linux-x64.AppImage
