Function query_sentiments 

pub fn query_sentiments(
    git: &dyn GitOps,
    query: &SentimentsQuery,
) -> Result<SentimentsOutput, GitError>

Collect sentiments from annotations across the repository.

In v3, sentiments are migrated into wisdom entries (gotcha for worry/unease, unfinished_thread for uncertainty/doubt, insight for others). This function reconstructs sentiment-like entries from wisdom entries by inferring the feeling from the category.

1. Determine which commits to examine
2. For each commit, parse annotation via parse_annotation
3. Map wisdom entries back to sentiment-like entries
4. Return newest-first
