feat(rust/hermes-ipfs): ipfs transport enable methods (#689)

* feat(hermes-ipfs): Add transport enable methods for P2P connectivity

  Add wrapper methods to enable TCP, QUIC, and DNS transports in
  HermesIpfsBuilder. These methods are required because connexa's
  TransportConfig disables all transports by default.

  - Add enable_tcp() method
  - Add enable_quic() method
  - Add enable_dns() method

  Without these methods, libp2p connections fail with "Multiaddr is
  not supported" errors. The methods must be called explicitly when
  building an IPFS node to enable P2P networking.

  Related to: #704

* chore(hermes-ipfs): Simplify connexa features to use 'full'

  Use the 'full' feature flag for connexa dependency instead of
  explicitly listing individual features. This is more maintainable
  and cleaner.

  Or if you prefer a shorter version:

* chore(hermes-ipfs): Format cleanup and transport config notes

  Format where clauses and add TODO comments documenting disabled
  default transport config and TLS/websocket options.
