Render Weekly Issue List
Read the JSON produced by query-tech-support-issues and render a Markdown list with Issue title/link, customer, engineer, KA status, and weekly hours.
python3 implementation.py \
--input /tmp/weekly-report/01-issues.json \
--output-dir ~/Documents/Obsidian/05-Work/weekly
Keep one row per engineer and Issue. Sum duplicate rows for the same engineer and Issue. Render internal work as 内部任务 and missing customer-master associations as 客户未关联.
