test(server): pin git config for fixtures and compare native realpaths#9570

Note

Pin Git config for test fixtures and switch path comparisons to native realpath

• Adds gitConfig.setup.ts to inject fixed Git defaults (no autocrlf, no signing, no filemode, longpaths, main branch) into the test environment, and loads it via vite.config.ts before server tests run
• Replaces Effect FileSystem realpath calls with Node's native realpath in RepositoryIdentityResolver and GitVcsDriverCore tests so path comparisons match platform behavior, including Windows short-name canonicalization
• Skips the newline-path worktree listing test on win32 because NTFS disallows newline characters in file names
• Behavioral Change: Git subprocesses spawned by server tests now inherit the pinned config entries; path equality assertions use native realpath rather than Effect's implementation

Note

Low Risk Test-only changes (Vitest setup, assertions, and one conditional skip); no production Git or VCS behavior is modified.

Overview Hardens the server test suite on Windows and mixed host Git configs without changing production code.

A new Vitest setup file injects fixed Git settings (core.autocrlf=false, no GPG signing, init.defaultBranch=main, etc.) through GIT_CONFIG_* so every git child process in tests ignores the developer’s ~/.gitconfig and Git for Windows defaults that were breaking byte-exact content checks.

Path equality assertions in RepositoryIdentityResolver and GitVcsDriverCore tests now use NodeFS.realpathSync.native instead of Effect’s realPath, so comparisons match Git’s long paths when temp dirs appear as 8.3 short names on Windows runners. The worktree test that uses a newline in a path is skipped on win32 because NTFS cannot create that name.
