Release v0.1.3: capture native Codex subagents and telemetry

[AxelDlv00]

Summary

• tail Codex rollout files during headless runs and discover direct/nested native subagents from thread_spawn provenance
• normalize child lifecycle states, both compaction record shapes, and current-request versus cached/cumulative token telemetry
• keep raw context telemetry append-only while showing only the newest context snapshot in the transcript
• bound live dashboard transcript work, preserve rejected attempts, serialize Lean checks, and improve long-session checkpoints
• remove the redundant execution/objective/durable-result strip from session logs
• bump every release surface to 0.1.3 and document the architecture, dashboard, CLI, and release notes

Claude inline subagent parsing remains unchanged. Post-run Codex ingestion remains as an idempotent reconciliation pass.

Verification

• npx tsc --noEmit
• npm run build
• python scripts/version.py --check
• git diff --check

It seems correct, and has been tested on two on my current projects, it can therefore be merged.
