`newServiceFixture` stops auto-pick from starting a grab, because none
of its tests is about the download and a detached `go m.grab(...)`
racing `t.TempDir()`'s cleanup is how they fail. It did that with
`MaxSizeMB: 1` -- and the size gates read `Candidate.TotalSize`, which
real providers fill and the fake leaves at zero. Zero is under every
ceiling, so the guard never fired and the race it was written to
prevent kept happening, roughly one run in fifteen:
TempDir RemoveAll cleanup: unlinkat ... : directory not empty
The guard is a format the fake never produces. Thirty consecutive
whole-package runs, none.
`TestManualDownloadSatisfiesRequestOnSuccess` was relying on the guard
being broken -- it is the one test here that wants the download -- so
it now clears the preferences itself rather than depending on a bug.

`check` failed on main with two failures in one package, and they are one
cause wearing two shapes:
service_test.go:66: state = "satisfied", want wanted
testing.go:1369: TempDir RemoveAll cleanup: ... directory not empty
Every test in service_test.go is about the durable Request that
StartDownload leaves behind, and none is about the download. But the
fixture is an anchored four-track request with a healthy provider, which
is precisely what AutoPickable says yes to -- so Manager.Start fired
`go m.grab(...)`, detached and with context.WithoutCancel, and the tests
raced it. Measured: the request reaches "satisfied" about 100ms after
StartDownload returns, so the first failure is the assertion reading the
next state, and the second is that same goroutine still writing into
t.TempDir() after the test returned.
The fixture now puts the candidate outside the auto-pick size window, so
the grab never starts. That is better than waiting for it: with no
goroutine there is nothing to be slow, and the tests state what they mean
without a timing assumption underneath. A test that does want the
download uses managerFixture and sets its own preferences.
It passed 20 runs under CPU load, but so did the broken version -- this
is a CI-only failure locally, so the cause was proved directly instead:
with the fixture's old preferences the request is observably "satisfied"
within 100ms of StartDownload, which is what CI read.
The durable "I asked for this" record was called Want, and the one-shot
search-and-grab attempt was called Request — names that didn't match
what either actually did. Want is now Request, and the old Request/Item
is now Download/DownloadItem, with a table-rename migration
(download_wants -> download_requests, old download_requests ->
download_downloads) safe against both fresh installs and existing data.
Every anchored manual download now upserts/reuses a durable Request
before running, so a "download now" that finds nothing is picked up by
the background reconciler automatically instead of just failing with
no trace — the gap that caused this session's repeated "no candidates
found" failures on the same album.
Also adds auto-download guardrails (file-size min/max with a preferred
target, allowed file types) that gate what the pipeline may grab
unattended, live-editable from a new settings section. The frontend's
wanted-view becomes downloads-view, with a new Downloads tab showing
attempt/transfer history that previously had no UI at all.
