fix: remove version from archive filenames for /latest/ redirect

Changed name_template from:
  {{ .ProjectName }}_{{ .Version }}_{{ .Os }}_{{ .Arch }}
To:
  {{ .ProjectName }}_{{ .Os }}_{{ .Arch }}

Now filenames are consistent across versions:
- claude-code-sync_linux_amd64.tar.gz (not _0.2.1_linux_amd64.tar.gz)
- claude-code-sync_windows_amd64.zip
- etc.

This makes /releases/latest/download/claude-code-sync_linux_amd64.tar.gz
work correctly as documented in README.
