Quick script to find active branches in a repo. Mostly a Gemini2.5 test

# Calculate the timestamp for 7 days ago from the current time
# Using the context's current time: Thursday, April 3, 2025 at 10:30:56 AM PDT
# If running this later, 'date -d "7 days ago" +%s' will use the actual current time.
# For consistency with the request context:
# CURRENT_DATE_STR="2025-04-03 10:30:56 PDT"
# ONE_WEEK_AGO_TIMESTAMP=$(date -d "$CURRENT_DATE_STR - 7 days" +%s)
# Or simply use the relative date for current execution:
ONE_WEEK_AGO_TIMESTAMP=$(date -d "7 days ago" +%s)
