Title duplication bug with non-alphabetic characters (Korean, Japanese, Numbers)

[hsp1020]

Steps to reproduce

this bug affects not only Korean but also Japanese, numbers, and other non-alphabetic characters where isLowerCase() returns false.

Examples:

Korean: 아기가 → 아기가기가
Japanese: ミッキー → ミッキーッキー
Numbers: 1923 → 1923923

Expected behavior

cloudstream/library/src/commonMain/kotlin/com/lagradost/cloudstream3/MainAPI.kt

fun fixTitle(str: String): String {
return str.split(" ").joinToString(" ") {
it.lowercase().replaceFirstChar { char ->
if (char.isLowerCase())
char.titlecase(Locale.getDefault())
else
char.toString() // [FIX] 'it' (word) -> 'char.toString()' (character)
}
}
}

Actual behavior

cloudstream/library/src/commonMain/kotlin/com/lagradost/cloudstream3/MainAPI.kt

fun fixTitle(str: String): String {
return str.split(" ").joinToString(" ") {
// Here, 'it' refers to the entire split word. (e.g., "아기가")
it.lowercase().replaceFirstChar { char ->
// Here, 'char' is the first character ('아').
if (char.isLowerCase())
char.titlecase(Locale.getDefault())
else
it // <--- Critical mistake!
// Here, 'it' refers to the entire word from the outer scope ("아기가"), not the first character.
}
}

Other details

Consequently, when the first character is not a lowercase letter (e.g., Korean, Kanji, or Numbers), the code replaces the first character with the entire word.
Example logic: Replacing '아' (first char) with '아기가' (entire word) results in '아기가' + '기가' = '아기가기가'.

Since I'm on mobile, I can't submit a PR, so I'm posting it as an issue.
