/**
 * Ingest provider documentation into the SQLite FTS5 index.
 *
 * Reads markdown files from docs/{provider}/*.md and chunks them
 * by heading (## or ###), storing each chunk with provenance metadata.
 *
 * Each markdown file can include a YAML frontmatter block with provenance:
 *   ---
 *   source_url: https://example.com/docs
 *   source_type: readthedocs
 *   upstream_version: 1.8.8
 *   crawled_at: 2026-03-26T00:00:00Z
 *   ---
 *
 * Files without frontmatter default to source_type: "curated".
 *
 * Usage:
 *   npm run ingest                    # ingest all providers
 *   npm run ingest -- --provider opta # ingest one provider
