What

Expose four libSceNet data exports: IPv6 loopback, node-local all-nodes and link-local all-routers addresses, plus sce_net_dummy. Their names, sizes, initial bytes and module identities agree in both version-labelled images. Those labels do not authenticate firmware provenance. The new loopback object remains distinct from the existing in6addr_loopback object.

Tested

• macOS x86-64: compiled the production network source and checked the linked image for the four data symbols, their bytes and alignment, and the distinct loopback object. This does not exercise the patched guest-import path or a full production build.
• Added checks to the existing guest_sce_net test and syntax-checked that source. The full test was not run. A standalone load of the dependency-incomplete network fixture failed during initialization, so it is not counted as a runtime test.
• Public-header audit, conventions and whitespace checks passed; all four names hash to their observed NIDs.
• The overlap checker scanned 1,597 open PRs but could not compare shared files in fix(libSceNet): stop Sackboy loading retries on peer sockets #5836, fix(libSceNet): report the receive queue length in sceNetGetSockInfo #9932, feat(libkernel): cancel blocked POSIX reads with owned operations #12682, fix(libkernel): preserve blocking sockets over nonblocking native transport #12688, feat(libkernel): cancel blocked POSIX writes with partial progress #12700 and feat(libkernel): support deferred cancellation in POSIX accept #12965 because those branches conflict with main. Their shared-file diffs were inspected and do not change these constants; future rebases may require reconciliation.
• No Linux, Windows, console or game run was performed.

Checked the four names against their NIDs (all hash to the expected ones), the address bytes (::1, ff01::1, ff02::2) and the new guest_sce_net checks, which only link with the change; merged.
