ci: use numeric-only pre-release identifier for MSI compatibility

The Windows MSI bundler maps the SemVer pre-release identifier to the
4th version field and requires it to be numeric-only and <= 65535, so
"0.4.0-pre.185" fails to bundle ("pre" isn't numeric). Use a single
numeric identifier instead: "<base>-<run_number>" (e.g. 0.4.0-185).

SemVer ordering is preserved (0.3.0 < 0.4.0-185 < 0.4.0-186 < 0.4.0) and
both channels keep building MSI on Windows, matching the installer type
existing stable users already have. promote.yml's suffix strip is
generalized to "-.*" to recover the stable version from the new format.
