`quak files` with a collection ID used to wait for a full refresh, which
on an empty cache fetched the files of every collection in the account.
It now reads the collection list, then that one collection's files
through the new `Library.freshFiles()`, and stores nothing. The files
print in the server's order, and no refresh progress lines appear. Each
file prints once, as the latest copy the server sent. `quak files`
without a collection ID still waits for a refresh.
Some tests ran `quak files` with a collection ID to fill the cache, to
show a refresh's progress or to show what `-q` hides. They now run a
command that still refreshes.
Model: opus-5-5
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 fatal lines, and is refused with -v; both are program options. Every non-zero exit logs one fatal line, so a run that exits 1 because files failed says how many and where to look. Every line reporting a failure is at error. --json changes stdout only, so backup and --json runs log their progress on stderr. withRetry and ApiClient report retries and requests through new callbacks.
