2026-09-26	perf python: Allow KeyboardInterrupt to propagate in LiveSession	Ian Rogers
	LiveSession.run() synchronously blocks while polling evlist for events. When running interactive tools or scripts from the terminal, KeyboardInterrupt exceptions raised via Ctrl-C must propagate so the caller can break out of the polling loop. Previously, LiveSession caught KeyboardInterrupt with an empty pass statement, swallowing the exception and preventing calling scripts from detecting the interrupt cleanly. Remove the empty handler so calling scripts receive KeyboardInterrupt and can perform clean teardown.

2026-06-30	perf python: Add LiveSession helper	Ian Rogers
	Add LiveSession class in tools/perf/python/perf_live.py to support live event collection using perf.evlist and perf.parse_events, avoiding the need to fork a separate perf record process.
