v0.8.0 — Codex runtime support

Codex runtime support

Agent Flow now watches Codex rollouts alongside Claude Code sessions in all three entry points: VS Code extension, pnpm run dev, and npx agent-flow-app. Sessions from both runtimes appear side-by-side, tagged by runtime.

Highlights

• Parses ~/.codex/sessions/**/rollout-*.jsonl (respects CODEX_HOME)
• Surfaces tool calls, reasoning, authoritative token counts, and handles auto-compaction
• Opt-out via agentVisualizer.runtime (extension) or AGENT_FLOW_RUNTIME env var (relay / npx)
• New AgentSessionWatcher abstraction — Claude and Codex watchers are now interchangeable, no vscode dependency in the runtime layer

Acknowledgements

Thanks to @BinaryOutlook for the initial Codex exploration in #2 — the prior art and bug report on auto-compaction helped shape this implementation.
