Auto add functions based on glob pattern

app.addFunctionsFromPaths('functions/*.ts');

Note, using glob pattern might be more convenient way to add function endpoint into Nammatham app, however, it may lose something:

• Type-safe End-to-end from backend to frontend by extract type from NammathamApp, however, during my plan this is overlapping the same thing that tRPC does, so, this may be don't care.
• Bundling ESM Tree Handshaking, right now Azure Functions v4 and Nammatham v2 (Make sure Azure Functions Adapter can bundle  #110) doesn't app bundling yet, considering issues later when those issues is fixed.

Example:

import { initNammatham } from '@nammatham/core';
import { AzureFunctionsAdapter } from '@nammatham/azure-functions';

const n = initNammatham.create(new AzureFunctionsAdapter());
export const app = n.app;

app.addFunctionsFromPaths('functions/*.ts');

app.start();
