fix(runner): normalize missing tool call IDs

[HAYDEN-OAI]

Summary

• carries forward fix: handle missing tool_call.id in runTools for providers #1946 while preserving the original @anishesg commit and explicit co-author credit
• generates a unique fallback ID when an OpenAI-compatible provider omits a tool call ID or returns an empty string
• normalizes IDs before completions are stored or emitted, keeping assistant tool calls and tool-result messages paired
• handles both non-streaming and streaming runners, including parallel calls to the same function

Context

GitHub rejected the maintainer push to the organization-owned fork even though the PR reports maintainer edits as enabled. This integration branch therefore merges the original PR commit and builds the corrected implementation on top of it rather than recreating the contribution separately.

Validation

• pnpm exec jest tests/lib/ChatCompletionRunFunctions.test.ts --runInBand
• pnpm exec tsc --noEmit
• focused ESLint and Prettier checks
• pnpm build

Closes #1528
