Two fixes for issue #9 (WW90T634DHE washer):
- observe: a busy device (e.g. a washer mid-cycle) intermittently returns an
empty/stub rep for a resource in the batch /device/0 sweep, which the batch
parser surfaces as {}. apply_rep would then replace the cached fields with
nothing, sending every entity on that resource -- the wash-setting and
detergent/softener dosing selects -- to "unknown" until the next good sweep.
A Samsung OCF resource never reports a genuinely empty state, so
ObserveManager.apply now drops an empty rep when the cache already holds
real data, keeping the last known-good value; a later sweep/notify with
real fields updates it normally. A first-ever stub is still applied so the
resource is known to exist.
- diagnostics: pkg_version("smartthings-local") reads the installed package's
metadata off disk (listdir + open + read_text), tripping HA's event-loop
blocking-call detector. Offload it to the executor. Audited the rest of the
package: config_flow's socket/crypto work and every coordinator DTLS call
are already offloaded via async_add_executor_job -- this was the only
blocking call left on the loop.
Adds regression tests for both.
