[WIP] Import inidividually expo warning

[Copilot]

• Analyze repository structure and understand the issue
• Identify that package.json exports field is missing entries for ./skiaChart and ./svgChart subpaths
• Understand that skiaChart.js and svgChart.js files exist and are properly built in lib/ directory
• Add exports entries for ./skiaChart and ./svgChart in package.json
• Fix import paths in skiaChart.js and svgChart.js to use .js extensions
• Fix TypeScript declaration file paths in skiaChart.d.ts and svgChart.d.ts
• Test the fix to ensure imports work without warnings
• Verify TypeScript support works correctly
• Run tests and linting to ensure no regressions

Summary: Fixed the expo warning "Attempted to import the module '...skiaChart' which is not listed in the 'exports'" by adding proper export entries in package.json for ./skiaChart and ./svgChart subpaths. Also corrected import paths to use proper file extensions and fixed TypeScript declaration paths to match the built directory structure.

The fix enables proper individual imports as documented in the Advanced Guides:

import SkiaChart, { SkiaRenderer } from '@wuba/react-native-echarts/skiaChart';
import SvgChart, { SVGRenderer } from '@wuba/react-native-echarts/svgChart';

<issue_description>following the instructions in Advanced Guides > Import individually i get the following warning message

WARN Attempted to import the module "/.../node_modules/@wuba/react-native-echarts/skiaChart" which is not listed in the "exports" of "/.../node_modules/@wuba/react-native-echarts" under the requested subpath "./skiaChart". Falling back to file-based resolution. Consider updating the call site or asking the package maintainer(s) to expose this API.

and typescript error TS2307: Cannot find module '@wuba/react-native-echarts/skiaChart' or its corresponding type declarations.</issue_description>
