fix: extracted Github project live demo URLs not being passed to LLM

[jlam323]

Description

Fixes #404
(Closes #404)

Summary of Changes

Updated convert_github_data_to_text() in transform.py:895-900 to include the live_url field when generating GitHub project prompt text for the LLM.

Reason for Change

While live_url was being extracted during repository data gathering, it was previously omitted from the formatted text context string. This prevented the LLM from considering project live demo links during candidate evaluations.

Verification

1. Clear caches
2. Rerun resume evaluator for the same resume.
3. Verified score and output text correctly reflect the live demo links in the GitHub portfolio's repos.

Output

   Metric                  | Before Fix (No live_url in prompt)     | After Fix (With live_url in prompt)

Above is a simple solution but alternatively we can further harden the live demo URL parsing if wanted

live_url = project.get("live_url")
if live_url and str(live_url).strip().lower() not in ("none", "n/a", "null", "live url if available"):
    github_text += f"   Live Demo URL: {live_url}\n"
