feat: universal TypeScript import alias support and internal path alias refactoring

[pingSubhajit]

Summary

This PR removes the Next.js dependency for import alias configuration and refactors all internal imports in the Unrag package to use TypeScript path aliases.

Changes

Part 1: Universal Import Alias Support

Previously, unrag init only patched tsconfig.json when Next.js was detected. Since Unrag is TypeScript-only, import aliases should work for any TypeScript project.

Modified files:

• packages/unrag/cli/commands/init.ts
  • Removed Next.js conditional check (lines 650-656)
  • Now always calls patchTsconfigPaths() for TypeScript projects
  • Updated output messaging from "Next.js" to "TypeScript"

Impact:

• Plain TypeScript projects (Bun, Deno, vanilla TS) now get tsconfig path aliases automatically
• Existing Next.js projects continue to work as before

Part 2: Internal Import Path Aliases

Refactored all internal imports to use clean path aliases instead of relative paths.

Created:

• packages/unrag/tsconfig.json with path mappings:
  • @cli/* → ./cli/*
  • @registry/* → ./registry/*
  • @test/* → ./test/*

Updated ~80 files with ~180 import changes:

• CLI commands and lib files (15 files)
• Registry modules (45 files):
  • Core modules
  • 12 embedding providers
  • 11 extractors
  • Store adapters (drizzle, prisma, raw-sql)
  • Connectors (notion, google-drive)
  • Rerank and eval modules
• Test files (20 files)
