Add a space between the version number and the date parenthesis

Change the version notation from "ver4.946(2026/08/05)" to
"ver4.946 (2026/08/05)" and fix every consumer of the old format:

- Version.cs: normalize all 318 History entries to "verX.XXX (date)",
  and make VersionAndDate/VersionValue length-independent (slice up to
  the closing/opening parenthesis instead of fixed offsets).
- CI (release / validate-wix-msi / build-arm64-portable /
  attach-arm64-experimental): accept an optional space in the version
  regex, tolerating both old and new formats.

Deployed clients are unaffected: ProgramUpdates.Check reads exactly
5 characters after "ver" on the first History line, independent of
the parenthesis position.
