/**
 * File extractor that parses a TypeScript source file into a tree element.
 * - Uses the TypeScript compiler API to parse the AST.
 * - Extracts exported, public, non-`_`-prefixed declarations as `tree-documentation` children.
 * - Overloaded declarations sharing a name are merged into a single `tree-documentation` with multiple `signatures`.
 * - Top-of-file JSDoc comment becomes the file's `content`.
 * - Sets `description` (a plain-text summary from the first JSDoc paragraph) on the file and every `tree-documentation` child.
 * - Sets `title` on every `tree-documentation` child — `name()` for functions and methods, `name` for other kinds.
 * - The file element itself has no `title` — a TS source file has no confident title source; renderers fall back to `name`.
