Merge pull request 'v0.9.4 — top bar shows app version instead of ◄ SHIP (#23)' (#25) from topbar-version into master

Pin the wide layout to the viewport (height:100vh + overflow:hidden on the
root), add min-height:0 to the BODY wrapper and 3-column grid so the flex
chain actually constrains, and make the OPERATIONS panel a flex column whose
PanelContent is the scroll area (header stays pinned; the Panel root's default
overflow:hidden would otherwise clip). Columns' existing overflow-y:auto now
scrolls inside their tracks. Narrow mode keeps natural body flow.

 # Changelog
 
+## v0.9.4 — 2026-09-29 08:29
+- Top bar (#23): the `◄ SHIP` label in the mission control header is replaced with the app version number (e.g. `v0.9.4`). The header reads it from `package.json` via the same `@/package.json` import that `/api/version` and the OpenAPI spec use, so there is a single source of truth — no second hardcoded copy.
+- e2e: no spec changes needed — no spec asserted on the old `◄ SHIP` label (the landing-page test only checks the SpaceWanderer heading). All 15 specs compile unchanged.
+
+## v0.9.3 — 2026-09-29 08:20
+- Layout (#21): only the middle column scrolls now — the app is pinned to the viewport (`height: 100vh` + `overflow: hidden` on the root in wide mode) so body-level scrolling no longer moves the side panes. Left/right columns keep their existing `overflow-y: auto`, so any overflowing content (e.g. a long planet list) scrolls inside its own track instead.
+- Added `min-height: 0` to the BODY wrapper and the 3-column grid — flex/grid items default to a content-based minimum size, which is what let the page grow past the viewport before.
+- The middle OPERATIONS panel became a flex column with its PanelContent as the scroll area (`flex: 1; min-height: 0; overflow-y: auto`): long tab content scrolls inside the panel while the "OPERATIONS // SHIP COMMAND" header stays pinned — without this, the Panel root's default `overflow: hidden` would have clipped it.
+- Narrow layout (<900px) is unchanged: stacked columns with natural body scroll (the viewport pin applies to wide mode only).
+- e2e: no spec changes needed — none use mouse.wheel/scrollTo, and Playwright scrolls click targets into view within any scroll container. All 15 specs compile unchanged.
+
+## v0.9.2 — 2026-09-29 08:00
+- WORLD MAP (#19): the bottom JUMP ROUTES button list is gone — jumps now happen by clicking galactic chart fields. Systems adjacent to the current one (the same set as before, undiscovered included) are clickable nodes with a pointer cursor and a `// JUMP` sublabel; the current system stays bright green with CURRENT, unreachable systems are dimmed (OFFLINE) and not clickable.
+- NodeGraph (`components/ui/node-graph.tsx`) gained two optional, backward-compatible additions: an `onNodeClick(id)` prop that turns non-disabled nodes into buttons (click + Enter/Space, role=button, aria-label, focusable), and a per-node `disabled` flag — while a jump is in flight every node locks, mirroring the old disabled-button behaviour.
+- The jump flow itself is unchanged: same POST /api/jump call, world state refreshed from the response (turn counter, current system, new routes), event log entry written server-side as before.
+- e2e: two smoke tests touched the removed buttons and were updated — "world map shows…" now asserts the adjacent systems render as clickable chart fields (role=button count matches API adjacency) and "jumping to an adjacent system" clicks the target node by its accessible name. All 15 specs compile; `jumpToFreshSystem` is API-driven and needed no change.
+
+## v0.9.1 — 2026-09-29 06:47
+- UI layout pass (visual only — no game logic or API changes): CARGO HOLD // INVENTORY moved out of the LOCAL SYSTEM tab into a persistent panel in the right column; the UPCOMING ENCOUNTERS placeholder was removed entirely; the SHIP DATA placeholder was merged into VESSEL METRICS.
+- Grid: `260px / 1fr / 240px` → `320px / 1fr / 360px` (left pane ~+23%, right pane ~50% wider).
+- Cargo state wiring follows the existing lifted-state pattern: MissionControl fetches `/api/system` on mount and owns the SystemState; LocalSystemPanel receives it as a prop, keeps its planet list + scan result + explore action, and reports each scan's response up via `onChanged` (same as ShipSystemsPanel) — so CARGO HOLD mirrors scans live with no polling.
+- VESSEL METRICS now carries the two SHIP DATA rows that had real values: SECTOR (current system name from the lifted state) and TURN (`ship.turn`). The rest was dropped — HULL INTEGRITY / REACTOR OUTPUT / CREW ACTIVE duplicate the existing progress bars, TOTAL MODULES duplicates the left column's "N ONLINE" badge, DRIFT VELOCITY has no game equivalent.
+- e2e: no assertion changes needed — the LOCAL SYSTEM tests only assert panel internals (header, EXPLORE buttons, SCAN RESULT) and API state; CARGO HOLD / UPCOMING ENCOUNTERS / SHIP DATA were never referenced by any spec. All 15 specs compile unchanged.
+
 ## v0.9.0 — 2026-09-29 02:47
 - EVENT LOG tab — the last of the seven tabs to go live (issue #11): the terminal now renders the save's real game events instead of a placeholder feed. Every action already appends an event row (new game, jump, scan, research, ship upgrade/expand/build, mission accept + completion); this issue adds the read side and the rendering.
 - New endpoint: `GET /api/events` → latest N events, newest first (`{id, turn, type, message, createdAt}`), auto-initializes like all other reads. Optional `?limit=` (default 50, cap 200; non-integers or out-of-range values → 400). OpenAPI spec in code updated (14 → 15 paths) with the Event schema enumerating the eight event types.
