/**
 * Token telemetry: measures real before/after token usage by simulating
 * what an AI agent would do with and without codesight context.
 *
 * Approach: for each standard task (explain architecture, add route, review diff),
 * measure the actual bytes of context that would be consumed.
 *
 * "Without codesight": count tokens from the files an AI would need to read
 * to discover routes, schema, components, config, etc.
 *
 * "With codesight": count tokens from the CODESIGHT.md output.
