fix: Correct exact match detection in fzf algorithm

The previous condition 'sidx === 0 && eidx === textLength' incorrectly
identified subsequence matches spanning the entire text as exact matches.
For example, searching 'path' in 'pxyath' would trigger the boost incorrectly.

The correct condition 'textLength === patternLength' ensures that when all
pattern characters match as a subsequence and both strings have the same
length, it must be an exact match.
