fix: throttle tap parallelism to prevent DB starvation Reduced from 10 firehose + 3 resync workers per tap (26 total concurrent DB writers across both taps) to 2 firehose + 1 resync per tap (6 total). Also use service-level cpus: 0.25 instead of deploy.resources.limits.cpus which only works in Swarm mode. The previous config was driving server load average to 100+ and making SSH/HTTPS completely unresponsive.
