Airport popup Relocate works for flying/repairing planes via queue (ISS-096, v0.49.0)

The airport popup's Relocate row now lists ALL planes instead of only
grounded ones; the click handler picks the endpoint by the selected
plane's current status — available → /fly (unchanged), flying/repairing
→ /queue so the destination is appended to the flight queue and chains
on landing. No-planes fallback reworded to 'No planes to relocate.'

E2E +1: relocation.spec.ts dispatches the starter on a leg via API,
slows the sim to 1x, opens the popup for a different airport, selects
the flying plane and clicks Relocate here — asserts the queue contains
the clicked ICAO while the plane still flies its original destination.

 # Changelog
 
+## v0.49.0 — 2026-09-22 07:25
+- **Airport popup Relocate now works for flying/repairing planes (ISS-096).** The Relocate row in the map's airport popup (`components/Map.tsx`) previously listed only grounded planes and showed "No grounded planes to relocate." when none was available. It now lists ALL planes from the latest snapshot, and the click handler picks the endpoint by the SELECTED plane's current status: `available` → `POST /api/planes/{id}/fly` (immediate relocation, unchanged), `flying`/`repairing` → `POST /api/planes/{id}/queue` (the destination is appended to the plane's flight queue and chains on landing). Success text is "Relocation started." for fly and "Added to queue." for queue; the no-planes fallback guard is reworded to "No planes to relocate." No API changes — both endpoints existed since v0.25.0/v0.46.0
+- **Tests.** E2E +1 (`e2e/relocation.spec.ts`): dispatches the starter plane on a leg via the API so it is flying, slows the sim to 1x so the leg cannot land mid-test, opens the airport popup for a different airport, selects the flying plane from the (now full) list and clicks "Relocate here", then asserts via state that the plane's `queue` contains the clicked airport's ICAO while it is still flying its original destination
+
+## v0.48.0 — 2026-09-22 06:55
+- **Leg distance shown on contracts (ISS-095).** `PackageState` gains `distanceKm` (`lib/game/state.ts`) — the great-circle origin→dest distance, computed server-side in `getStateSnapshot()` from the airport GeoJSON already loaded for live-plane math (same `haversineKm` as flight movement; 0 if a coord is missing). Shown in two places via new `formatKm()` (`lib/format.ts`, integer km, no space before "km"): the on-board contract line (`EGCC → GMME 554km €23,826.00 …`) and the job-list row (`€37,408.00 215km Perishables 0.4t …`). OpenAPI spec updated in lockstep; nothing stored
+- **Tests.** Unit: `app/api/state/route.test.ts` asserts every package's `distanceKm` equals the haversine of its airports' coordinates (computed with the same lib/geo helper); `lib/openapi.test.ts` pinned key list gains `distanceKm`; new `formatKm` test in `lib/format.test.ts`. E2E: `right-pane.spec.ts` +2 assertions (job-row distance span matches /^\d+km$/, generic and hook-created package), `actions.spec.ts` +1 (on-board line)
+
+## v0.47.0 — 2026-09-21 23:01
+- **Job payoff retuned so weight dominates (ISS-090).** `REWARD_PER_KG` in `lib/game/seed.ts` rises from €0.5/kg to €2.0/kg — the linear form is unchanged, only the constant moves. Before, the weight term was small vs base+distance, so heavier jobs barely paid more (a 1000 km leg: €3,250 @500 kg → €5,000 @4,000 kg — per-kg rate fell from €4.59 to €1.01) and there was no sense in taking heavy jobs; after the retune the same leg pays €4,000 / €11,000, so weight clearly drives payoff. Safe for viability: fuel burn (`lib/sim/movement.ts`) is weight-independent, so this only raises income
+- **Tests.** `seed.test.ts`: stale test name "… 0.5 * weightKg …" made generic; new literal pins in the `rewardFor` formula test — `rewardFor(1000, 4000) === 11_000` and `rewardFor(1000, 500) === 4_000` — so future retunes are deliberate. All other reward assertions recompute through the exported constants and pass unchanged
+
 ## v0.46.0 — 2026-09-21 22:32
 - **Queue consumption on dispatch (ISS-088).** `flyPlane` (`lib/game/actions.ts`) now consumes `queue[0]` when the requested destination IS the first queued leg, so a landing never chains a zero-distance self-hop (the "phantom hop" — a→a completing instantly before reaching the real next leg). Flying to a non-first queued leg stays an explicit override and leaves the queue untouched; the persisted queue is written back in the same update
 - **Engine auto-chain hardening.** `deliverPackages` (`lib/sim/engine.ts`) gains two guards: (1) defensive skip — if `queue[0]` equals the arrival airport (only reachable from legacy/corrupt rows now that dispatch consumes), it drops the leg without flying; (2) full-tank backstop — if the next queued leg does not fit even a full tank, the plane grounds as `'available'` with the queue kept intact instead of chaining an unflyable leg (mirrors `flyPlane`'s 409 without throwing mid-tick)
