feat: opt-in new Sweep provide system

[guillaumemichel]

Integrate the DHT SweepingReprovider as opt-in feature in Kubo.

Note that the SweepingReprovider cannot make use of the accelerated DHT client due to kubo interfaces restrictions.

• Depends on feat: Reprovide Sweep libp2p/go-libp2p-kad-dht#1082 👈 Remaining work is mostly documented there
• Part of Improve the providing subsystem in Kubo — IPFS/2025 ipshipyard/roadmaps#6, Most Kubo users can reliably advertise their data into the Amino DHT — IPFS/2025 ipshipyard/roadmaps#7 and Kubo users can more directly control which data is advertised — IPFS/2025 ipshipyard/roadmaps#8

Initial integration checklist:

• Add reprovider.Reprovider to IpfsNode
• Build SweepingReprovider
  • For dual.DHT
  • For fullrt.FullRT
• Add SweepingReprovider options in kubo config
• Replace all occurrences of Provide() with the appropriate method from reprovider.Reprovider (see interface) if Reprovide Sweep is enabled.
  • see Provider interface libp2p/go-libp2p-kad-dht#1093
  • see Decentralizing new blocks notification (avoid providing everything) boxo#963
• Refactor how IpfsNode.Provider and IpfsNode.Reprovider are constructed (only 1 is needed)
  • Rename the new module Provider instead of Reprovider ??
• Add smoke tests
• Changelog
• Config docs
• Merge Reprovide Sweep libp2p/go-libp2p-kad-dht#1095
• Merge boxo companion PR refactor: use the new Reprovide Sweep interface boxo#995

Gateway Conformance test failing even without any new code (see here). Either test or new dependencies broken.
