Closes the v1.11 §35.7 forward-work item. Network tab now shows real-time R/W throughput (KiB/s) per interface, computed from delta of rx_bytes/tx_bytes between successive 7th-tick refreshes. Source code already landed (network.rs + app.rs + render.rs). This commit captures full v1.16 docs: - Improvement plan §40 (Network Throughput) - CONSOLE-TO-KDE §3.3.2 v1.16 - RATATUI-APP-PATTERNS §13.14 (audit table +16) + §14 (5755 LoC, 52 tests) Implementation summary: - New rx_kbps: f64 + tx_kbps: f64 fields on NetInterface - New NetInfo::read_with_throughput(prev, dt_secs) - Wall-clock dt (shared prev_refresh_secs with v1.14 + v1.15) - saturating_sub on bytes prevents underflow - 3 new unit tests (formula + underflow + zero dt) - 52/52 total tests pass Math sanity check (verified by unit test): prev=1MB, now=5MB, dt=2sec → 1953.125 KiB/s prev > now → saturating_sub → 0 Cross-compile SHA256: 053f1a0cca5185637d0316d56f5cf5832cf2e754b689bc24edf16ea5d0404fa2.
