karim 38b048ad41 G1000: two-way sim sync, more PFD/MFD fidelity, authentic dialogs
Sync (FlyWithLua companions in plugins/ + server/fmssync.js):
- FMS flight-plan two-way sync (App <-> in-sim FMS) via fms-sync.lua
- G1000 UI-state publish (page/range/inset) via ui-sync.lua + CDI source,
  baro, map-range follow
- Terrain awareness: elevation grid probe (terrain-probe.lua) -> red/yellow
  MFD overlay vs aircraft altitude

PFD:
- AFCS mode annunciation bar from autopilot _status datarefs
- CDI source GPS/VLOC colouring, BRG1/BRG2 pointers + DME windows, marker beacons
- magenta speed/altitude trend vectors, selected-altitude alerting
- time-based (frame-rate-independent) smoothing for attitude/heading/tapes

MFD:
- nav data bar (DTK/ETE/active leg), airways overlay from earth_awy.dat,
  compass rose anchored to the ownship

Dialogs (NEAREST/FLIGHTPLAN/DIRECT-TO/PROCEDURES):
- flat, square, embedded G1000 look (no shadow/rounded/transparency)
- compact lower-right placement, no close X (softkey toggles), single window
- NEAREST 2-line entries (ILS/VFR, COM freq, runway length), PROC action menu

Service worker: network-first HTML so reloads pick up new builds (cache v2).

# FlyWithLua companion — FMS two-way sync
X-Plane's Web API can't write a flight plan into the FMS. `fms-sync.lua` runs
inside X-Plane (via FlyWithLua, which has the FMS SDK) and syncs the shared
cockpit plan ↔ the in-sim FMS through two files in `Output/fms-sync/`.
## Install (sim PC only)
1. Install **FlyWithLua NG+** (free): copy its plugin folder into
`<X-Plane>/Resources/plugins/FlyWithLua/`.
2. Copy the scripts into `<X-Plane>/Resources/plugins/FlyWithLua/Scripts/`:
- **`fms-sync.lua`** — flight-plan two-way sync
- **`ui-sync.lua`** — G1000 UI state (page / range / inset)
- **`terrain-probe.lua`** — terrain-awareness elevation grid for the MFD
3. Restart X-Plane (or *FlyWithLua → Reload all Lua script files*).
The log shows `[glass-cockpit] FMS sync active`.
The bridge (desktop app / `node server/bridge.js`) must run on the **same PC**
as X-Plane, so both see `<X-Plane>/Output/fms-sync/`.
## What you get
- **App → Sim:** load/build a plan in the web cockpit → it appears in the 3-D
G1000 and the autopilot can fly it.
- **Sim → App:** build/edit the plan in the real FMS → it shows on every tablet.
- **Terrain:** the MFD TERRAIN map colours real scenery elevation red/yellow
relative to your altitude (probed live by `terrain-probe.lua`).
A 3-decimal lat/lon signature de-dupes the round-trip, so the two sides never
loop. Waypoints are pushed as lat/lon legs (exact route; in-sim idents are
generic — route accuracy over cosmetics).
