85314553 - Exporters: decode a one-token graph a token at a time, and keep a static cache at its traced length

Exporters: decode a one-token graph a token at a time, and keep a static cache at its traced length A dynamic export can have a one-token decode graph too (Qwen3.5's), so the prompt goes through it a token at a time whenever its graph was traced on one token, not only when the export is static. A static export records its cache length, and `generate` builds the cache at that length: a call needing more raises. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
