fix: CLI updates use installer scripts from the selected release

[hatayama]

Summary

• CLI updates and Unity Settings installs now download installer scripts from the selected CLI release tag.
• Release automation now verifies that the tagged installer scripts are reachable before publishing native CLI assets.

User Impact

• Users can trust that the installer script matches the release version being installed, instead of depending on mutable main or v3-beta branch content.
• A release now fails early if its tag does not expose the .ps1 and .sh installer scripts that updates will use.
• Reviewers can see the sample versions in installer tests as fixtures, not as the current shipped version.

Changes

• Build installer script URLs from the resolved CLI release tag in both Unity editor install commands and Go CLI self-updates.
• Remove the stable/beta branch selector used only for installer script downloads.
• Add a PowerShell release smoke helper that checks scripts/install.ps1 and scripts/install.sh under a specified release tag.
• Run that helper in the native CLI publish workflow after the release tag exists and before asset upload.
• Update editor and Go tests, clarify installer version fixtures, and regenerate checked-in native CLI binaries.

Verification

• go test ./internal/update ./internal/cli
• uloop compile
• uloop run-tests --test-mode EditMode --filter-type regex --filter-value ".*NativeCliInstallerTests.*"
• scripts/check-go-cli.sh
• scripts/test-check-release-installer.ps1 on Windows PowerShell
• scripts/test-check-release-installer.ps1 on pwsh
• scripts/test-native-cli-publish-workflow.sh
• scripts/check-release-installer.ps1 -Version cli-v3.0.0-beta.13
• codex-review v3-beta with no accepted/actionable findings

📝 Walkthrough

Walkthrough

Refactors CLI installer URL construction to use GitHub release tags (cli-v<version>) instead of branch references; removes branch/source-ref indirection; updates Go and C# implementations, tests, and CI to validate release-tagged installer script URLs.

Changes

CLI Installer URL Release-Tag Refactoring

Layer / File(s)	Summary
Go installer implementation refactor Packages/src/Cli~/internal/update/installer.go	Removes the SourceRefForVersion helper and branch/source-ref constants; updates ScriptURL to build download paths using ReleaseTag(version) directly.
C# installer URL construction Packages/src/Editor/Infrastructure/CLI/NativeCliInstaller.cs	BuildInstallerScriptUrl now inserts the provided releaseTag into the RAW_CONTENT_BASE_URL path directly, removing the indirection via SelectInstallerSourceRef.
Remove unused CLI constants Packages/src/Editor/Domain/CliConstants.cs	Deletes STABLE_INSTALLER_SOURCE_REF and BETA_INSTALLER_SOURCE_REF public constants no longer used by URL construction.
Update Go and C# tests Packages/src/Cli~/internal/update/installer_test.go, Packages/src/Cli~/internal/cli/update_test.go, Assets/Tests/Editor/NativeCliInstallerTests.cs	Tests now expect installer script URLs under cli-v<version>/scripts/ (e.g., cli-v3.0.0-beta.3/.../install.sh, cli-v3.0.0/.../install.ps1) and centralize test release/version constants.
CI/workflow and release verification .github/workflows/build-and-test.yml, .github/workflows/native-cli-publish.yml, scripts/test-native-cli-publish-workflow.sh	Load new PowerShell helper/test scripts in the Windows test step, add a conditional publish-time step to run scripts/check-release-installer.ps1 with RELEASE_TAG, and add shell tests that assert the workflow contains and orders this verification step.
