Tauri's MSI bundler errors on non-numeric pre-release identifiers: ``` failed to bundle project `optional pre-release identifier in app version must be numeric-only and cannot be greater than 65535 for msi target` ``` This blocks v0.6.5-rc.1 (and any `-rc.N` / `-beta.N` / `-alpha.N` tag) from producing the Windows MSI, which in turn skips compose-latest-json (it needs: build-windows), leaving the release workflow fix from PR #23 unvalidated. The constraint is Windows-specific (MSI inherits the 4-part numeric PE resource version). Fix by computing a numeric-only `wix.version` from tauri.conf.json at build time — strip everything after `-` so `0.6.5-rc.1` becomes `0.6.5` for MSI metadata only. The app's embedded semver (what the updater compares, what `env!("CARGO_PKG_VERSION")` returns) stays untouched, so pre-release tags still behave as pre-releases everywhere except the Windows installer's Add/Remove Programs display.

Summary
Tauri's MSI bundler rejects non-numeric pre-release identifiers, which blocked the v0.6.5-rc.1 release workflow run (mac + linux built fine, but Windows MSI errored with "optional pre-release identifier in app version must be numeric-only"). With Windows failing, `compose-latest-json` (which needs: build-windows) never ran, so PR #23's release-workflow fix was not actually validated.
Fix
Compute `wix.version` at build time by stripping the pre-release suffix from `tauri.conf.json`'s version — `0.6.5-rc.1` → `0.6.5` for MSI metadata only. Passed into `tauri build` via the same `--config` override that already sets `signCommand`.
