If you used the TUI and then installed the desktop app, the TUI could stop launching entirely — dying with opentui is not supported on the current platform, even though nothing about your platform had changed. This release fixes that, adds a one-command way to check your install, and makes every Linux and macOS build prove it actually runs before it ships.

• The TUI no longer breaks after you use the desktop app. Both apps share ~/.empryo, and the desktop's startup refresh was deleting native libraries it doesn't ship but the TUI depends on. The desktop is now fully self-contained — it reads its runtime from inside its own app bundle and never writes to the shared directory. Each surface now owns only the files it installs.
• Installs repair themselves. The installer keeps a pristine copy of the native runtime, so a TUI whose libraries were already wiped restores them on the next launch instead of staying broken. This also protects you if you're still running an older desktop build.
• A missing runtime finally says so. Instead of the misleading "not supported on the current platform", you get the exact file that's missing and how to fix it — and the crash report keeps the full message rather than a bare Error.

• `empryo doctor` — checks that the native runtime loads and that tree-sitter parses, then prints OK or the precise failure. Run it any time an install misbehaves; it's also what our release now runs against every build.

• Every macOS and Linux build is now executed before release — Linux inside a container, Intel macOS under Rosetta — and must load its native library and parse real code, not merely print a version number. A stale or mismatched native library can no longer reach a download link.
