Marc Billow f45bd6a72c laundry: discover and offer cloud "Download" cycles (issue #342) 
A washer whose course table includes "Download"/"Downloaded" runs whichever
program the SmartThings cloud last pushed down. Those programs are now
selectable from the ordinary cycle select, so a downloaded Jeans or Sports
cycle can be started without giving the appliance internet access.

The device turns out to enumerate them itself. `CloudExtraCourse_` on
/course/vs/0 lists one byte per downloaded program, and byte 2 of a
program's payload is exactly that slot id -- verified against all nine
programs on the reporter's WW5000C and against the WA55A7700AV dump already
in the corpus. So nothing here is hardcoded: the appliance says which
programs exist, the payloads are learned by watching what it reports, and
the names come from the user.

That last part is unavoidable rather than a shortcut. A payload is only
visible while its program is loaded, and the appliance never reports a name
for one. So cloudcourse.py persists what has been seen (same rationale as
learned.py's mode store), a Repairs issue tells the owner how many programs
are still unaccounted for, and an options-flow step collects the names. A
program appears in the cycle select only once it is both learned and named.

Selecting one issues the only two-token options write in the codebase --
the course token has to switch to Download in the same write, or the
appliance accepts the program token and silently ignores it (confirmed on
hardware). The Download course code is learned by observation but never
applied until the user confirms it: tokens in this array are replaced by
prefix and never evicted, so a stale program token can appear alongside an
unrelated course, and acting on that would start the wrong wash cycle. For
the same reason a stale token is never reported as the running program.

Also of note:

- There is no single "Download" course code. The WW5000C uses 87, the
  WA55A7700AV uses 17 -- same Table_02. Any per-table lookup would have
  been wrong on one of the only two devices available to check.
- Payloads are replayed byte-for-byte and never decomposed or rebuilt.
  Bytes 5/7/9 do decode to temperature/rinse/spin on the WW5000C, 9 for 9,
  and produce nonsense on the WA55A7700AV -- so that decode is written up
  in docs/investigations/download-cycle.md and not shipped, and the
  read-only sensors it would have enabled were dropped.
- The store reaches the registry as a namespaced synthetic field merged
  onto /course/vs/0's rep at read time, so exists_fn/rep_fn/options/write_fn
  all see it through their existing signatures. It never enters the state
  cache, so it can't be polled over, written to the device, or land in a
  diagnostics dump.
- A name that would render identically to another cycle in the same
  dropdown is rejected in the flow: the select maps a chosen label back to
  a raw value by matching display text.

Non-English catalogs carry the new strings in English for now; they need
real translations.
