Bug

streamText silently skips local tool approvals when a later context message follows the approval response

Reproduction

• Added runnable reproduction at examples/ai-functions/src/reproduction/issue-17033-trailing-context-skips-tool-approval.ts.
• The control approval executed the local tool exactly once when the approval response was the final message.
• Appending a user message after the same approval response caused the tool to execute zero times instead of exactly once.
• The provider prompt contained the unresolved tool call and trailing user context without a tool result.
