Add learning progress tracker for tutorial series

Problem

Readers following a multi-part tutorial series have no way to track which parts they have completed. When they return to the site, they must remember where they left off manually.

Proposed Solution

Implement a client-side progress tracker using localStorage:

const STORAGE_KEY = 'codeharborhub_progress';

function markPageAsRead(pageId) {
  const progress = JSON.parse(localStorage.getItem(STORAGE_KEY) || '{}');
  progress[pageId] = { completedAt: Date.now() };
  localStorage.setItem(STORAGE_KEY, JSON.stringify(progress));
  updateSeriesProgressBar();
}

Display a progress bar at the top of each series index page showing X of N parts completed. Add a checkmark badge to completed parts in the table of contents sidebar.

Additional Context

Level 2 feature. Progress is per-browser only and resets on cache clear — a known limitation to document. An optional "Export progress" button lets users back up their data.
