Closes #557

What changed

fan out Web Push across devices with a configurable concurrency ceiling (default 8)
preserve ordered sends within each device
stop retrying later threads on a failed endpoint during the same poll
document the production setting

Verification

RED observed for bounded cross-device concurrency, per-device failure short-circuiting, and poll-loop configuration wiring
