# PostToolUse + Stop: sync token usage from the Claude Code transcript.
#
# Claude Code does not pass token counts to hooks, but it does pass the
# path to the session transcript (.jsonl), which records per-message
# `usage`. We hand that path to the SDK server, which parses the transcript
# and SETS the cumulative totals (absolute, idempotent — safe to call after
# every tool and again at Stop). The orchestrator later reads these via
# /usage/status to finalize the spawn-session row and the usage dashboard.
#
# Fire-and-forget — never block Claude on this. Always exit 0.
