fix: simplify version display

[graycreate]

Show only version name (e.g., 2.3.13) without version code

[Copilot]

Pull request overview

This PR attempts to simplify the version display in the Settings screen by removing the version code from the display format. However, the implementation does not achieve this goal due to the underlying implementation of Utils.getVersionName().

Key Issue:

• The Utils.getVersionName() method already appends the version code to the version name (as versionName + "." + versionCode), so removing the explicit version code display in parentheses does not actually remove it from the UI—it just changes the format from "2.3.13 (56)" to "2.3.13.56"

[Copilot]

The change does not achieve the stated goal of showing only the version name. Looking at the implementation of Utils.getVersionName() (line 347 in Utils.java), it returns packageInfo.versionName + "." + packageInfo.versionCode, which means the version code is still included in the display. The version code was previously shown in parentheses (e.g., "2.3.13 (56)"), and now it will be shown as a dot-separated suffix (e.g., "2.3.13.56"). To truly show only the version name without the version code, the Utils.getVersionName() method needs to be modified to return only packageInfo.versionName, or a separate method should be used here.

	versionPref.setSummary(getAppVersionNameOnly());

	* that may be added by {@link Utils#getVersionName()} (e.g. "2.3.13.56" -> "2.3.13").

	private String getAppVersionNameOnly() {
	String fullVersion = Utils.getVersionName();
	if (fullVersion == null || fullVersion.isEmpty()) {
	return fullVersion;
	}
	int lastDot = fullVersion.lastIndexOf('.');
	if (lastDot > 0) {
	return fullVersion.substring(0, lastDot);
	}
	return fullVersion;
