/**
 * Represents a Java `.properties` file.
 *
 * Properties files consist of key=value pairs, one per line,
 * with `#` used for comments. This file format is commonly
 * used by tools like SonarQube, Gradle, and other JVM-based
 * ecosystem tools.
 *
 * The object passed as `obj` can be a nested structure. Nested keys are
 * flattened into dot-separated property keys on synthesis. For example,
 * `{ sonar: { sources: "src" } }` produces `sonar.sources=src`.
 *
 * This means `addOverride` uses dot notation as a path separator,
 * consistent with ObjectFile/JsonPatch semantics.
 *
 * @example
 * new PropertiesFile(project, 'sonar-project.properties', {
 *   obj: {
 *     sonar: {
 *       projectKey: 'my-project',
 *       sources: 'src',
 *     },
 *   },
 * });
 *
 * // Produces:
 * // sonar.projectKey=my-project
 * // sonar.sources=src
