fix: support anthropic stream requests

Fixes #46

Modification

• Switch ModelRunner from run_tools_async to stream_events_async for Anthropic stream compatibility.
• Only pass parallel_tool_calls=False for anthropic / vertexaianthropic models to avoid breaking non-Anthropic providers.
• Prioritize stream error handling before tool-followup decisions, so failed final events are not treated as successful tool continuation.
• Add regression tests for:
  • non-Anthropic path not receiving parallel_tool_calls
  • stream error taking precedence over tool follow-up
• Keep related tape-context stream compatibility updates and corresponding tests in this PR.
• Use ASCII status tags ([OK] / [ERROR]) in telegram_send.py for PowerShell-friendly output.

Tests

• Existing tests: uv run pytest passed
• Manual verification: covered by regression scenarios for Anthropic stream error + provider compatibility paths

Code Quality Checks

• uv run ruff check . passed
• uv run mypy passed

can you help fix the lint?

Sure, I have fixed the lint errors. Let me know if there's anything else

Hi @cUp1d,

Thanks. I just got back from vacation and don’t have a suitable API to test right now. I’m leaning toward moving the provider compatibility logic to Republic. Would love to hear your thoughts since you’re the expert on this now.

Welcome back! I have some Anthropic API keys available for testing. Happy to share it with you and bub project collaborators.

Agreed that moving the compatibility logic to republic is the cleaner approach. one thing i noticed — there's an open PR (#22) to move republic into the bub monorepo. might make sense to land that first so the fix can be done in one place? or if that's not happening soon i can open a separate PR on republic directly. let me know what you think.

@cUp1d Thanks a lot

Re: #22, I don’t think moving republic into the bub monorepo is fully on the roadmap.

Handling this directly in the republic repo sounds great to me. Feel free to open the PR there.
