Fix v0.1.0 crashing at launch (welcome screen layout loop) - #12

Conversation
The v0.1.0 release, built against the macOS 26.5 SDK, aborts on launch when the Full Disk Access banner is showing: "The window has been marked as needing another Update Constraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window." The banner's wrapping text makes the welcome screen's minimum height depend on its width, and with the newer SDK that minimum feeds into the window's constraints, so each pass changes the next one. Giving the welcome screen zero minimum width and height keeps its size out of the window's constraints. Local SwiftPM builds record SDK 15.0 and never hit this, which is why it only showed up in the CI build. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Summary
The v0.1.0 download crashes about a second after launch on macOS 27. It's likely to crash on macOS 26 too. It dies with an uncaught
NSGenericException:Cause
vtoolreproduce the crash.Fix
Give the welcome screen's outer frame zero minimum width and height. Its size then no longer feeds into the window's constraints. The banner keeps its
.fixedSizetext, so nothing truncates.Testing
Built locally and also stamped as SDK 26.5 to match CI. Launched at four restored window sizes: 800×800, 1200×800, 1800×800 and the 800×500 minimum. Without the fix, every size crashes under SDK 26.5. With it, every size runs, for both builds.
Follow-up: add a launch smoke test to the release workflow so a build that crashes at launch can't be published.
