feat(ci): control symbol stripping via NO_STRIP matrix var

The workflow now passes a per-platform NO_STRIP setting into the
Tauri build environment. This allows builds to retain symbols when
needed, improving debugging and crash analysis without changing the
default behavior for other targets.

- Add matrix no_strip values for Windows and Ubuntu
- Export NO_STRIP into the build environment for Tauri
