perf(cmdk): Score each candidate field individually in scoreNode

Instead of joining label, details, and keywords into a single string
and running fzf once, score each field independently and return the
best match. This has two benefits:

- Avoids false cross-field subsequence matches that could arise when
  the tail of one field and the head of the next happen to satisfy a
  pattern across the join boundary.
- Allows fzf's built-in exact-match bonus to fire naturally (e.g. when
  the query equals the label exactly), without needing a manual boost
  at the call site.
