HIG 0.3.0 — market colours, touch-safe CSS and import fixes

• Every JS export now has a default condition beside import. Jest/jest-expo, require() and Metro's CommonJS resolution can import HIG entries instead of failing with ERR_PACKAGE_PATH_NOT_EXPORTED.
• @bloxwap/hig/react/css is touch-safe. Every :hover rule now sits behind (hover: hover) and (pointer: fine), so taps no longer leave buttons dimmed or ghost buttons filled. Hosts can delete their sticky-hover overrides, and tests/touch-css.test.ts keeps the gate in place. HIG controls also get no tap highlight, touch-action: manipulation, no long-press selection, :active press feedback, 16px text fields on touch, overscroll containment, and safe-area padding on edge sheets and dialogs.
• Native market-direction colours: useColors() adds up and down (defaulting to buy/sell), HIGProvider marketColors overrides them and is inherited, and NumberReadout, Usd, Percent and AnimatedNumberReadout accept tone="up" | "down". New types: HIGMarketColors, HIGMarketColorRole and HIGTableColorRole. colorTable() and useBrandColors() now return the table roles only. This replaces the mobile app's local patch of 0.2.0.
• Native AnimatedNumberReadout hides its underlying reading with clear white (#ffffff00) instead of transparent. Android Fabric reads 0x00000000 as unset and drew that reading in black under the reels.
• Motion: web button presses ease over 160ms on the standard curve instead of snapping. AnimatedNumberReadout uses the standard HIG curve (tokens.easing.standard) on web and native. Native digit reels mount 20 rows instead of 30, a third less to render per animated place.
• Native test consumers track Expo SDK 58.0.23, which expects react-native-safe-area-context ~5.11.1, and the peer range now accepts it.
• Accept @bloxwap/chart 0.4.0: the required peer is now ^0.3.0 || ^0.4.0, and HIG develops, smoke-tests and documents against 0.4.0. Chart 0.4.0 only adds indicator APIs, so PriceChart and chartTheme are unchanged.
• Pin @bloxwap/font 0.1.4. Its web CSS now loads unicode-range subsets, so pages download only the scripts they render. The variable sources behind @bloxwap/hig/native-fonts and @bloxwap/hig/og-fonts are byte-identical to 0.1.2, so the generated TTFs and their SHA-256 hashes are unchanged; only the manifests' source version changes.
• The docs site now installs @bloxwap/haptic 0.3.0 and @bloxwap/sfx 0.2.1, inside HIG's supported peer ranges, instead of the older 0.1.0 builds.
