Replace relative imports (../../../) with TypeScript path aliases (@/)
throughout the codebase for improved readability and maintainability.
- Configure path alias in tsconfig.json with @ mapping to src/
- Update esbuild from v0.13.12 to v0.25.9 for modern features
- Add alias configuration to esbuild.config.mjs for build support
- Refactor build configuration to use context API for watch mode
- Update all component and utility imports to use @/ prefix
- Fix incorrect CSS import paths in habit and settings components
- Maintain consistent import structure across 148 files
This change simplifies import statements, makes the codebase more
maintainable by avoiding deeply nested relative paths, and modernizes
the build toolchain.
