* fix(cli): keep phrase-level CJK and Thai transcripts as separate cues wordsToCues inferred whether entries were already grouped into phrases by testing for internal whitespace. Chinese, Japanese, Thai and the other scripts written without inter-word spaces never satisfy that test, so their phrase-level transcripts were treated as word-level and re-grouped into a single cue covering the whole clip. A three-phrase Chinese transcript produced one cue; the same transcript in English produced three. The failure was silent: the export succeeded, and the user found out by watching the captions. For entries with no whitespace at all, fall back to entry length when they are in a spaceless script. Whisper emits word-level tokens for those scripts one or two characters at a time, while a phrase-level cue runs to several times that. The median is used so one long token cannot declare word-level input pre-grouped, and a couple of short cues cannot declare a real transcript word-level. --preserve-cues still forces the same thing, and behaviour for space-separated scripts is unchanged. Fixes #3353 * test(cli): pin the spaceless phrase length threshold
