Replace deprecated 'twitter' dependency with maintained alternative

[coderabbitai]

Context

The twitter package (v1.7.1) is deprecated and unmaintained since 2017. It targets the legacy Twitter v1.1 REST API, which has been substantially deprecated by X/Twitter since 2023–2024.

Issue

Many v1.1 endpoints are now removed or restricted, making this dependency unreliable with current X APIs.

Proposed Solution

Replace with a maintained alternative such as:

• twitter-api-v2 (recommended)
• Official X SDK
• Other supported client library

This issue was created as a follow-up to the TypeScript migration to keep the scope manageable.

Review Twitter Type Definitions

When upgrading the twitter package or related dependencies, please review the use of custom type definitions vs the official @types/twitter package.

Context from PR #452:

• Currently using custom ambient module declaration in types/twitter.d.ts
• Suggestion to replace with official @types/twitter package (version 1.7.4 available on npm)
• Using official types eliminates maintenance burden and potential type divergence

Reference: #452 (comment)

Action items:

• Evaluate if @types/twitter covers all required types
• If suitable, remove types/twitter.d.ts and add @types/twitter to devDependencies
• Test that existing imports continue to work with official types
