Phase 3 — build.sh produces a working .app bundle

[eonist]

Part of the deployment pipeline umbrella: #3

Goal

bash build.sh compiles a universal binary, assembles a .app bundle, ad-hoc signs it, and zips it to dist/RunnerBar.zip. Double-clicking the .app shows the gray dot in the menu bar.

Acceptance test

1. Run bash build.sh — exits cleanly, no errors
2. dist/RunnerBar.zip exists
3. Unzip and double-click RunnerBar.app — gray dot appears in menu bar, no Gatekeeper dialog
4. Verify universal binary: lipo -archs dist/RunnerBar.app/Contents/MacOS/RunnerBar prints x86_64 arm64

build.sh must

• Compile with --arch arm64 --arch x86_64
• Assemble dist/RunnerBar.app/Contents/{MacOS,Resources}
• Copy binary and Info.plist
• Ad-hoc sign: codesign --force --deep --sign -
• Zip with ditto -c -k --keepParent
• Write dist/version.txt
