## Message

```
perf(web): avoid repeated terminal metadata scans (#9747)

Build one ordered terminal metadata index per immutable snapshot. Reuse unchanged session wrappers and thread groups across consumers, with separate environment targets.

Keep numeric ordering, picker ties, attach state, and subscription lifetimes unchanged. Let retired snapshots and groups be collected.

Created with GPT-6 Astra (preview) in Codex.
```
