fix: stream(legacy): include delta.reasoning alongside reasoning_summary

FammasMaz · web-flow · commit b0de3a2e6f50 · 2025-08-21T22:36:37.000+02:00
In legacy/current compatibility mode, stream both `delta.reasoning_summary` and
`delta.reasoning` (string) for reasoning deltas. This ensures clients that
expect `choices[0].delta.reasoning` as a string (e.g., OpenCode) render
reasoning without schema errors.

Change made only to legacy to avoid breakage with other software
