* refactor: integrate duration into matchScore instead of using pre-filter
Duration matching was handled as a binary pre-filter with fallback,
inconsistent with how title, specificity, and album are scored via the
matchScore system. Move duration into matchScore as a boolean field
ranked between title similarity and specificity level, making all
match criteria use the same hierarchical comparison.

* refactor: use duration proximity score instead of boolean match
Replace the binary durationMatch bool with a continuous durationProximity
float64 (0.0-1.0) using 1/(1+diff). This removes the hard 3-second
tolerance cutoff, so closer durations are always preferred over farther
ones without an arbitrary cliff edge.
