Subject: [PATCH] Quality pass: build system & infrastructure (#76)

- Fix error masking in build-ghostty.sh: replace blanket `|| true` on zig
  build with proper exit code capture; add cleanup trap for temp files;
  guard WUFFS/SIMD copies with explicit file checks; fix ranlib stderr
- Add VERSION file as single source of truth for app version; read it in
  bundle.sh and generate-build-info.sh (emits BuildInfo.version)
- Add binary existence check in bundle.sh before bundling
- Add `make test` target that discovers all packages with Tests/ dirs
- Align mise.toml build task to use `make build` instead of raw swift build
- Expand CI: test job loops over all packages; add shellcheck lint job
- Expand CONTRIBUTING.md with make test docs and make build guidance
- Add header comments to all build scripts

 **Note:** Code signing is not required for development. Unsigned builds work normally for local testing. Official releases are signed and notarized automatically via GitHub Actions.
 
 ### Running Tests
 
 ```bash
-swift test        # or: mise test
+make test         # Preferred — runs all package tests
+swift test        # Also works (runs root package tests)
+mise test         # If using mise
 ```
 
-Tests use the Swift Testing framework (`@Test` macros).
+Tests use the Swift Testing framework (`@Test` macros). Currently, tests exist
+in `CrowCore`. When adding new functionality to any package, include a test
+target in that package's `Package.swift` and add tests.
