List activity summaries for a date range. Returns ONLY compact identification data (id, date, name, type, distance, moving_time, elevation, heart rate, speed, training load, fitness/fatigue, calories, source).

Returns 100+ fields far beyond what list_activities provides, including: power (avg, weighted, FTP, W', joules), cadence, pace/GAP, zone times (HR/power/pace), performance metrics (efficiency factor, variability index, decoupling, polarization index), weather conditions, temperature, RPE/feel, intervals summary, achievements, gear, and tags. Always use this when answering questions about a specific activity.
