Notable features and improvements

This release is an important step toward solving the DHT bottleneck for self-hosting IPFS on consumer hardware and home networks:

• DHT Sweep provider is now the default - The efficient keyspace-sweeping provider system is enabled by default (Provide.DHT.SweepEnabled=true), reducing load spikes for nodes with large content collections.
• Fast root CID providing for immediate content discovery - By default, Kubo makes root CIDs discoverable immediately after ipfs add or ipfs dag import, typically under 1 second.
• Detailed statistics with ipfs provide stat - ipfs provide stat shows detailed statistics including queue sizes, reprovide schedules, and worker utilization. Use --all for complete metrics.
• Provider state persists across restarts - The provider now resumes where it left off after restarts, with automatic catch-up for content that missed reprovide cycles during downtime.
• Automatic UPnP recovery after router restarts - Fixed automatic port forwarding recovery after router restarts, maintaining connectivity without manual intervention.
• RISC-V support with prebuilt binaries - Official linux-riscv64 prebuilt binaries bring IPFS to open hardware architectures.
