# Summary: Launches Thorium/Chromium with a dedicated profile while filtering Flutter flags.
# Description:
# Kills any existing Thorium instance, resolves the desired profile path, and starts the browser backgrounded.
# Drops Flutter-specified params like --disable-extensions, --bwsi, and user-data-dir so the chosen profile stays intact.
# Traps termination signals to cleanly kill the spawned browser once Flutter stops.
# Waits in the foreground so Flutter tooling can detect when the browser exists and the test run completes.
