/**
 * Cursor keeps no token usage in its local storage (bubble `tokenCount` fields are always zero),
 * but the Cursor dashboard exports per-request usage events as CSV ("Usage" -> export). An export
 * dropped in `<analytics dir>/imports/cursor/*.csv` is imported as telemetry rows:
 * - input_tokens = "Input (w/o Cache Write)", cache_write_tokens = "Input (w/ Cache Write)",
 *   cache_read_tokens = "Cache Read", output_tokens = "Output Tokens";
 * - each event is attached to the local Cursor session whose message is closest in time (events
 *   are written 1-3 s after the local bubble); events without a local conversation go to one
 *   technical `task` session per export file, so their tokens are still counted;
 * - rows are keyed by the event values, so overlapping exports never count an event twice.
 * Only technical columns are read: the user column is used solely to refuse multi-user team
 * exports and is never stored; cost, repository, PR and agent identifiers are ignored.
