Add Scripts/update_build_number.sh (the shared indie build script) and wire it into both targets as a postBuildScripts phase. On each build it sets CFBundleVersion to the git commit count, writes a BuildDate key (surfaced by IndieAbout), and tags the marketing version. Run as a post-build phase rather than post-compile so it lands after the Info.plist/dSYM exist, which also avoids an Xcode 26 build cycle. Bumps MARKETING_VERSION to 2.1.
