Fix reusable workflow secret name (PR_REVIEW_TRACKER_PROJECT_TOKEN)

[hatton]

[Claude Opus 4.8] The secret rename landed after #1 was merged, so main still declares the old PROJECT_TOKEN while caller repos now pass PR_REVIEW_TRACKER_PROJECT_TOKEN. That mismatch makes caller runs fail at startup (startup_failure). This aligns the reusable workflow with the callers.

Greptile Summary

Fixes a secret name mismatch between the reusable workflow and its callers. After the rename landed post-#1, the reusable workflow still declared PROJECT_TOKEN while callers were already passing PR_REVIEW_TRACKER_PROJECT_TOKEN, causing startup_failure on every caller run.

• Renames the workflow_call secret declaration from PROJECT_TOKEN to PR_REVIEW_TRACKER_PROJECT_TOKEN and updates the single ${{ secrets.PR_REVIEW_TRACKER_PROJECT_TOKEN }} reference in the GH_TOKEN env var — the change is atomic and complete.
• Updates the header comment to note that callers must map the secret explicitly and that BloomBooks now requires a fine-grained PAT instead of a classic PAT.

Important Files Changed

Filename	Overview
.github/workflows/pr-review-tracker.yml	Renames the workflow_call secret from PROJECT_TOKEN to PR_REVIEW_TRACKER_PROJECT_TOKEN in both the declaration and the single usage, and updates the header comment to reflect fine-grained PAT requirements; change is consistent and complete.
