Initial commit: offline flight planner (Rust, PFPX-class)

Clean-room reproduction of PFPX: route generation + IFPS validation + OFP.
Independent design — official ICAO/EUROCONTROL data only (RAD, FRA points,
IFPUV oracle); no community FPL sources.

Workspace crates: core (routing/discover/rad/navdata/perf/export),
cli, server, rad (Annex parser), gui (Tauri v2 + React + MapLibre).
Route discovery: oracle-in-the-loop repair against Eurocontrol IFPUV.
