/**
 * Opt-in local telemetry.
 *
 * Principles (non-negotiable):
 *   1. Opt-in only — default is off. A fresh install collects nothing.
 *   2. Local only — this module writes to ~/.blockrun/telemetry.jsonl.
 *      No network transmission, ever. A future opt-in "upload" feature
 *      would be a separate module with its own consent gate.
 *   3. No content — never log prompts, tool inputs, tool outputs, file
 *      paths, or wallet addresses. Count-level aggregates only.
 *   4. Inspectable — the log is plain JSONL, one record per session.
 *      `franklin telemetry view` prints it. Users see exactly what was
 *      recorded before ever considering sharing it.
 *   5. Revocable — `franklin telemetry disable` stops future writes
 *      and leaves historical data intact. `franklin telemetry reset`
 *      (future) would wipe the log.
 *
 * Data model is a sanitized projection of SessionMeta. Nothing original
 * is stored here that isn't already derivable from the session meta
 * files — telemetry is just a stable, aggregation-friendly view of
 * information the user already has.
