Add `preChunked?: string[]` to `IndexDocumentInput` — when provided, `indexDocument` skips the markdown chunker and uses the caller's chunks directly. `LibScopeLite.index()` now checks `doc.language`: if set and supported, it pre-chunks the content with `TreeSitterChunker` and passes the result as `preChunked`. Falls back silently to the text chunker on any error (tree-sitter not installed, parse failure, etc.). Consumers set `language: "cpp"` (or any supported alias) on their `LiteDoc` and get function/class-boundary chunks automatically. Docs updated to note this as the preferred approach over using `TreeSitterChunker` directly. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

* fix: export TreeSitterChunker and CodeChunk from libscope/lite TreeSitterChunker was compiled but not re-exported from the ./lite entry point, making it inaccessible to consumers using the package exports map.
