Fix OAuth redirect_uri truncation and bot API syntax errors

🔧 Fix Critical OAuth and Bot API Issues

Problem

The previous PR #112 introduced two critical issues that broke the main branch:

1. OAuth redirect_uri truncation - Users getting "redirect_uri is not associated with this application" error
2. Bot API 500 errors - Content submission failing with "A server e... is not valid JSON" error

Root Causes

1. OAuth URL construction was using string concatenation instead of proper URL encoding
2. Bot API syntax errors with duplicate try-catch blocks causing server crashes

Solution

• ✅ Fixed OAuth redirect_uri using URLSearchParams for proper encoding
• ✅ Removed duplicate try-catch blocks in bot API
• ✅ Added debugging logs for OAuth URL construction
• ✅ Fixed syntax errors that caused 500 responses

Technical Changes

// Before (causing truncation)
const authUrl = `https://github.com/login/oauth/authorize?` +
    `client_id=${this.clientId}&` +
    `scope=${this.scope}&` +
    `state=${this.generateState()}&` +
    `redirect_uri=${encodeURIComponent(redirectUri)}`;

// After (proper encoding)
const params = new URLSearchParams({
    client_id: this.clientId,
    scope: this.scope,
    state: state,
    redirect_uri: redirectUri
});
const authUrl = `https://github.com/login/oauth/authorize?${params.toString()}`;

Files Changed

• github-auth.js - Fixed OAuth URL construction
• api/github/create-content-pr.js - Fixed syntax errors

Impact

• 🎯 Resolves OAuth authentication failures
• 🎯 Fixes content submission bot API errors
• 🚀 Restores full functionality to main branch
• 🔍 Improves debugging with better logging

Testing

• OAuth redirect_uri now properly encoded
• Bot API syntax errors resolved
• No linting errors
• Proper error handling maintained

Branch naming: Follows convention with fix/ prefix
