Subject: [PATCH] fix: stream(legacy): include delta.reasoning alongside
 reasoning_summary

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
