+.SYNOPSIS
+Parses a logcat filter string into an array of filterspec tokens.
+
+.DESCRIPTION
+Splits a whitespace-separated logcat filter string into individual "tag[:priority]"
+filterspec tokens, as accepted by `adb logcat` and by Appium's logcatFilterSpecs
+capability. A tag on its own means "tag:V" (verbose); "*:S" silences everything else.
+Empty tokens are removed.
+
+.PARAMETER FilterString
+The raw logcat filter string. May be null or empty, in which case an empty array is returned.
+
+.EXAMPLE
+ConvertTo-LogcatFilterSpec -FilterString "godot:V sentry-native:V *:S"
+Returns: @('godot:V', 'sentry-native:V', '*:S')
