Agent(execution=ExecutionConfig(max_budget=1.00)))."), keep the existing
sys.exit(1) call, and update the exception handling block (the code that
currently prints those lines and references e and sys.exit(1)) to use this
single print instead.

In-place mutation of resolved_exec violates agent isolation by modifying shared ExecutionConfig instances
resolved_exec.max_budget = max_budget (line 752) mutates the object returned by resolve_execution. Since resolve_execution returns the same ExecutionConfig instance that was passed in (line 1314-1315 in feature_configs.py), this silently modifies the caller's original object. Any other agent holding a reference to that shared config would observe the unexpected budget value — a direct violation of the no-shared-mutable-state principle.
Use dataclasses.replace() to create a new instance instead:

Use a single-line actionable budget error to meet CLI acceptance criteria.
The current output spans multiple lines; the issue acceptance criteria calls for a single-line user-facing message with exit code 1.

Remove unused BudgetExceededError import at line 4214.
The import from praisonaiagents.errors import BudgetExceededError is not used in the code block following line 4214. Error handling is properly delegated to _execute_agent_with_budget_handling, which already performs a guarded import with fallback (lines 4087–4092). The eager import at line 4214 is unnecessary and can fail on module/version mismatches, preventing the agent initialization code from running at all.

‼️ 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.

resolve_execution returns the same object when execution is already an ExecutionConfig instance, so resolved_exec.max_budget = max_budget mutates the caller's original object. Any code that passes a shared config to multiple agents will see the budget value propagate unexpectedly to all of them. Copying the config before mutating it avoids this.
