/**
 * kiro cost provider: per-turn credit usage from local session files.
 *
 * Two on-disk shapes (both undocumented — fail-soft everywhere, D2):
 * - IDE: ~/.kiro/sessions/<workspace-hash>/sess_<uuid>/messages.jsonl with
 *   usage_summary events: promptTurnSummaries[].usage (credits, fractional).
 *   session.json alongside carries workspacePaths for project matching.
 * - CLI: ~/.kiro/sessions/cli/<uuid>.json with
 *   session_state.conversation_metadata.user_turn_metadatas[].metering_usage.
 *
 * Cursor: "<n>" — count of usage events already consumed from the file
 * (files are append-only per session).
 *
 * Design: design.md §3, D2
