Merge pull request 'v0.9.7 — local system refreshes after jump, no page reload needed (#30)' (#32) from local-system-refresh into master

WorldMapPanel owns the world state and applied the /api/jump response
locally, so MissionControl's lifted /api/system state (LOCAL SYSTEM tab,
CARGO HOLD, SECTOR row) stayed on the previous system until a full refresh.
The panel now takes an onJumped callback that MissionControl wires to an
/api/system refetch after every successful jump.

 # Changelog
 
+## v0.9.7 — 2026-09-29 09:59
+- LOCAL SYSTEM no longer shows the previous system after a jump (#30): WorldMapPanel owns the world state and applied the `/api/jump` response locally, so MissionControl's lifted `/api/system` state (which drives the LOCAL SYSTEM tab, CARGO HOLD and the SECTOR row) went stale until a page refresh. The panel now takes an `onJumped` callback that MissionControl wires to a `/api/system` refetch after every successful jump — same failure policy as the mount fetch (keep old state on error).
+- e2e: new smoke spec — click-to-jump on WORLD MAP, wait for the chart's turn counter to update, switch to LOCAL SYSTEM and assert its header shows the NEW current system from `/api/world` (no `page.reload()` workaround; one jump per run/retry, same pattern as the existing jump test).
+
+## v0.9.6 — 2026-09-29 09:41
+- The active operations tab now survives a page refresh (#27): the selected tab ID is persisted to `localStorage` (`sw-active-tab`) on every change and restored on mount when it matches one of the seven valid tab IDs (unknown/stale values fall back to WORLD MAP). The Radix Tabs are controlled for this; SSR and first client render still agree on the default, so there is no hydration mismatch.
+- e2e: new smoke spec — click CREW, reload, assert `aria-selected=true` again (fresh context per run/retry, no API state touched, idempotent).
+
 ## v0.9.5 — 2026-09-29 09:13
 - Fixed the production freeze reported after the v0.9.3 (#21) deploy ("entire UI system is now fucked"). Root cause was NOT the #21 layout change (verified healthy across all 7 tabs and multiple viewports — no clipping, middle pane scrolls internally, side panes fixed): it was world name generation. `makeName` draws from a finite pool of 16×8=128 system names with an unbounded rejection loop, so once a save grew past ~128 systems (turns of play / e2e jump loops), any jump into an undiscovered system spun forever on Node's single thread — sql.js runs synchronously, so the whole process blocked and EVERY API route hung, leaving all panels stuck at LOADING.
 - `makeName` (lib/game/world.ts) now falls back to numbered variants (`Kepler Drift 2`) once the pool is exhausted, so it always terminates; `makeCrewName` (lib/game/crew.ts) gets the same guard — the roster has no cap and its 16×22=352 pool would eventually exhaust too.
