fix: fuzzy match ignored short words like 'a' causing false matches

The fuzzy matcher's qw.includes(nw) check matched any artist with
'a' in their name against any query — 'shannon' contains 'a', so
'a silver mt. zion' and 'have a nice life' matched every search.

Added minimum length guards:
- qw.includes(nw): nw must be >= 3 chars (filters 'a', 'an', 'I')
- editDistance: both words must be >= 4 chars (prevents short-word
  false positives like 'mt' matching 'me')
