 * Resolves library source file paths to their actual file system locations.

 * Handles three types of library imports:
 * 1. Relative paths - files within the project root
 * 2. Path-mapped imports - imports resolved through tsconfig paths
 * 3. External library imports - imports resolved through node module resolution
 *
 * For external libraries with watchSourceDirectly enabled, follows source maps
 * to find the original TypeScript source files instead of declaration files.
 *
 * If watchSourceDirectly is not explicitly provided, it will be automatically
 * determined based on whether any variants use tsconfig path aliases.
