Progress tracking feature

Add Progress Tracking Tools (Learning Goals, Completions & Streaks)

Summary

This PR introduces a Progress Tracking system to the InterviewReady MCP server.
It allows users to track learning progress, set study goals, and maintain a streak based on daily activity — helping learners stay motivated during interview preparation.

This feature is fully MCP-tool compatible and works alongside existing reminder & content tools.

New Tools Added

set-learning-goals

Define weekly and monthly learning targets for a user.

Example:

{
  "userId": "user123",
  "weekly": 5,
  "monthly": 20
}

---

mark-content-completed

Log completed content such as blogs, resources, or courses.

Example:

{
  "userId": "user123",
  "contentId": "blog-1",

}

Automatically:

• records timestamp

• prevents duplicate entries

get-progress

Returns the user's current learning status.

Example output:

  "completed":[
    { "contentId":"blog-1","type":"blog","timestamp":1767572472955 }
  ],
  "goals":{"weekly":5,"monthly":20},
  "streakDays":1,
  "lastActivityDate":"Mon Jan 05 2026"
}

Implementation Details

• Progress is stored persistently in a JSON datastore
• Streaks are calculated based on daily activity

This design keeps the implementation simple and aligned with the current repo structure.
