Handle zero-budget correctly in shared stats.
remaining_budget currently uses a truthiness check, so max_cost=0.0 is treated as “no budget limit” and returns None instead of 0.0/negative values.
💡 Suggested fix
"remaining_budget": (
- round(self.max_cost - total_cost, 4) if self.max_cost else None
+ round(self.max_cost - total_cost, 4) if self.max_cost is not None else None
),📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Do not run daemon-state sync I/O directly on the event loop.
_update_state_if_daemon() performs blocking filesystem/JSON operations. Calling it directly in async retry paths can stall the loop and delay other async work.
💡 Suggested fix
- self._update_state_if_daemon()
+ await asyncio.to_thread(self._update_state_if_daemon)
@@
- self._update_state_if_daemon()
+ await asyncio.to_thread(self._update_state_if_daemon)Based on learnings: “All I/O operations must have async variants; never block the event loop with sync I/O in async context.”

Fixes #1856
Summary
This PR addresses three concrete wrapper layer violations of PraisonAI's core principles (DRY, protocol-driven, minimal API, multi-agent + async safe):
1. Duplicate arun() method definitions
Problem: Both FrameworkAdapter Protocol and BaseFrameworkAdapter class defined arun() twice, creating dead code and maintenance confusion.
Solution:
2. CLI tool resolution bypass
Problem: CLI's _load_tools() bypassed the unified ToolResolver, directly accessing TOOL_MAPPINGS, causing CLI/YAML/Python inconsistency.
Solution:
3. Async scheduler divergence
