Motivation

Refactors Chip toward the v6/MD3 API and implementation direction.

• Extracts Chip-specific sizing, color, and typescale values into a dedicated tokens.ts file, following the pattern used by other recently modernized components (e.g. Badge).
• Simplifies the internal layout: the ripple/state-layer is now rendered in its own layer behind the content instead of being nested inside it, and content spacing is derived from tokens instead of inline math.
• Removes the press-time elevation animation (Animated.timing driven scale/elevation on press) in favor of a static elevation derived from the elevated and disabled props.
• Reworks selected, outlined, disabled, icon/avatar, and close-icon color resolution (getChipColors in utils.ts, renamed from helpers.tsx) to better align with MD3 state and color roles, including a dedicated ripple color and an avatar selected-overlay color.
• Adds a proper minimum touch target (48dp) via hitSlop, and moves the close icon into TouchableRipple for consistent ripple/state-layer feedback.
• Removes the compact and showSelectedOverlay props, which are no longer part of the MD3-aligned API (the selected overlay is now handled automatically for avatars).
• Changes the default mode from flat to outlined.

The example app has been updated to match the new API (e.g. dropping now-removed showSelectedOverlay usage) and to showcase MD3-oriented Chip states.
