TestRoutesCompatNoPeersBeyondCaptures extends the negative peer
assertion from 6 hardcoded files (f10-f15) to all 98 ROUTES golden
files using a generic, data-driven approach.
For each golden file, the test derives expected peer pairs from
capture SrcIPs (subnet routes, direct node IPs) and DstPorts
(destination node IPs, route CIDRs), handling IP dash-range format
(100.64.0.0-100.115.91.255) and wildcards. It then asserts that no
unexpected CanAccess=true pairs exist.
Also adds addSrcIPToBuilder helper and deriveAllPeerPairsFromCaptures
for comprehensive peer derivation from golden data.
