Comment blocks in cmd/minstrel and 30 smaller internal packages, rewritten
to rule 32's standard with each citation read in context: task, milestone
and rule ids go, and so do the stories they were attached to ("used to",
"Before #N", measurements from one install, quotes, pointers to Fabled
Librarian's records and to docs/superpowers files that are not in the
repo). Where a story wrapped a real constraint, the constraint stays as a
present-tense fact.
Comments that had gone stale are corrected:
- taste.Config: the tuned values are overlaid by internal/recsettings;
it is no longer "a later follow-up".
- StorageConfig: the data dir holds art, caches and the stream secret,
not only playlist covers.
- the Subsonic album list and getUser comments describe what they do
today rather than a milestone that would change it.
Checked: the non-comment token stream of every changed file matches
HEAD, and gofmt -l is empty.

// Package mood maps folksonomy tags (from the track_tags cache) to a small
