A command that exits 1 because files or albums failed now ends with one
fatal line saying how many failed and where to look, so -q never leaves
a non-zero exit unexplained: backup points to failures.json, backup-metadata
to mlDataError in each file's JSON, and fix-missing-thumbnails to its
Failed files list. The progress callbacks of the backup, the metadata
backup and the thumbnail helpers take a level, so every line that reports
a failure is logged at error. The library's operation names are shown in
plain words. The README says which lines are error and warning, and which
summary lines --json replaces.

Every line quak prints on stderr now goes through one log, in
src/cli-log.ts, at one of six levels. The default, info, prints what quak
printed before. -v adds each retry and the start and end of each refresh
and ML data fetch; -vv adds each request with its result. -q prints only
the line a failing command exits with, and is refused with -v. Both are
program options. withRetry reports retries through a new onRetry, and
ApiClient reports requests through a new onRequest; the CLI logs what
they report. --json now changes stdout only, so backup and --json runs
log their progress on stderr.
