Margin Call Version 0.8.2 released

## v0.8.2 — Stone Theme & Guided Run Polish

- **Stone theme global** — dark warm-stone aesthetic applied to all components (left panel, header, right panel) regardless of layout. `isStone = true` hardcoded everywhere; `ThemeContext` always returns `{ isStone: true }`.

- **RightPanelGrid always shown** — desktop right panel always uses the grid-style `RightPanelGrid` component (table view removed from right panel). Turn indicator moved inline with headline; removed from top bar.

- **Grid layout default** — stock grid is now the default layout and appears first in the settings toggle.

- **HeadlineCard removed from desktop center column** — headline is rendered inside `RightPanelGrid` only, avoiding duplication.

- **Mobile capital review bar redesign** — dark gradient background, thicker bar, glowing target amount, inset pulse animations (`anim-review-*-inset` keyframes) since the strip is flush with screen edges.

- **Capital review popup stone theme** — stone gradient background, muted per-option borders, amber hover state via `useState`.

- **Active intel top border pulse** — the colored top stripe on intel-affected stock cards now pulses opacity + box-shadow glow via `anim-intel-stripe` CSS animation. Color fed dynamically via `--stripe-glow` CSS custom property.

- **Guided run step-aware interaction gates**:
- Step 1: spotlight AIPC only (`tutorialFocusStocks=['AIPC']`), all other stocks dimmed + non-interactive, tooltip pinned top-right, no scrim overlay.
- Step 7 (intel shop): full intel section highlighted with amber glow + `brightness(1.35)`, all stocks blocked (`tutorialFocusStocks=[]`).
- Step 8 (end turn after intel): stocks with active intel glowing + read-only, Incoming shop blocked, Your Signals free; only End Turn clickable.
- Steps 0–6 and 8: intel scrollable body overlaid (End Turn stays interactive).
- `GuidedRun` hidden during `anim.active` so resolution animations play unobstructed; stock focus cleared immediately on End Turn press.

- **Guided run tooltip improvements** — stone gradient tooltip theme, `anchor` prop for fixed positioning (top-right / bottom-left), `noScrim` option per step, merged style props bug fix.
