WiX requires the app version to be numeric-only (major.minor.patch). Pre-release tags like v0.2.1-test1 or v0.2.1-rc1 caused the MSI bundler to fail with 'optional pre-release identifier must be numeric-only and cannot be greater than 65535'. Strip the pre-release suffix (e.g. 0.2.1-rc1 → 0.2.1) before writing to tauri.conf.json. The git tag and GitHub Release name still use the full version string.

Problem
The release workflow failed when a tag with a pre-release suffix was pushed (e.g.
v0.2.1-test1):WiX (the Windows MSI bundler used by Tauri) only accepts versions in
major.minor.patchformat. Any pre-release suffix containing letters (-test1,-rc1,-beta) is rejected.Fix
Strip the pre-release suffix before writing the version to
tauri.conf.json. A newversion_msioutput holds the clean version (0.2.1-test1→0.2.1). The git tag and GitHub Release name still use the full original version string.Test plan
v0.2.1-rc1and confirm the MSI build succeedsv0.2.1-rc10.2.1
