Function main

main(): Promise<void>
CLI entry point — the function dist/index.js invokes when a user runs enquire-mcp from the terminal. Builds the commander program, registers every subcommand (serve, serve-http, setup, install-model, install-ocr-lang, build-embeddings, index, eval, doctor, clear-cache, clear-index, clear-embeddings, gen-token), wires the shared retrieval flags via addAdvancedRetrievalOptions, and parses process.argv. Each subcommand action handles its own errors and sets process.exitCode; main itself does not catch — an unexpected throw propagates to the top-level handler in index.ts which prints it and exits non-zero.

Returns Promise<void>
A promise that resolves once argument parsing + the selected subcommand's action have completed (commander's parseAsync).
Example
```
// dist/index.js
import { main } from "./cli.js";
main().catch((e) => { console.error(e); process.exit(1); });
```
v3.9.0-rc.28 (external-audit M-4) — the entry point previously had zero TSDoc.
