Feature: Celestia-backed NPM Registry

[tac0turtle]

Summary

Expose an npm-compatible registry API backed by Celestia blobs through Apex.

Example usage:

npm publish --registry=https://apex.dev/npm
npm install package-name

Motivation

The npm ecosystem currently depends on centralized infrastructure.

Using Celestia DA would provide:

• Permanent package availability
• Censorship resistance
• Decentralized package distribution
• Verifiable package storage

Architecture

Package tarballs would be chunked and stored as blobs.

Implementation Steps

1. Implement blob transaction submission in Apex
2. Store package tarballs as blobs
3. Store package metadata in SQLite
4. Expose npm registry compatible endpoints
