Rename worker_report entry point from main.py to core.py

[extreme4all-ai]

Summary

worker_report is the only base that uses main.py as its entry point module instead of core.py (consistent with all other 11 bases).

• bases/bot_detector/worker_report/main.py should be renamed to bases/bot_detector/worker_report/core.py
• projects/worker_report/pyproject.toml:21 — update entry point from bot_detector.worker_report.main:run to bot_detector.worker_report.core:run

Proposed Change

1. Rename bases/bot_detector/worker_report/main.py → core.py
2. Update the script entry point in projects/worker_report/pyproject.toml
3. Update any internal imports that reference main
