deps: bump iroh 0.98.1→0.98.2, blake3 1.8.4→1.8.5, tokio 1.52.1→1.52.3, mainline 6.0.1→6.1.2

Cargo.lock-only. All bugfix patches plus a mainline minor:
* iroh 0.98.2: div-by-zero protection in process_datagram; don't
  abort connection attempts on concurrent empty EndpointAddr.
* blake3 1.8.5: fix LTO build on Arch Linux ARM.
* tokio 1.52.3: reverts LIFO-slot stealing perf regression from 1.51.
* mainline 6.1.2: avoid eager DNS resolution of default bootstrap
  nodes; reduce peer-discovery target_size 20→10 (MTU overflow);
  configurable bind addr; loosens its digest pin to 0.11.
