Expand linux-kpi wireless scaffolding, consolidate desktop plan, remove historical report

Add channel/band/rate/BSS/RX-TX structures to linux-kpi wireless
scaffolding (mac80211.rs, wireless.rs, net.rs, C headers), extend
redbear-iwlwifi linux_port.c with comprehensive PCIe transport, and

desktop path document. Remove stale INTEGRATION_REPORT.md (1388 lines)
in favor of current local/docs/ references. Update AGENTS.md, README,
and docs index to point to the new plan.
