With Discord closed, every now-playing edge (two per track: the immediate
publish and the poll's) tried the IPC socket and the crate logged
"find_pipe: could not find pipe" each time, so a listening session read
as an error stream. A failed connect now sets a five-minute deadline,
logs one line at info, and later edges push nothing until it passes;
opting the integration in again clears the deadline. The crate's own
warning is demoted to error in the default log filter. Pure backoff rule
covered by a unit test.
The Discover preferences store also logged "unavailable" when its lazy
init ran before the session restored; that startup order is normal and
the handle is rebound on activation, so it is a debug line unless a real
user directory fails to open.
