fix(coding-agent/modes): added checks to skip writing error messages to

- Added checks to skip writing error messages to stderr when stopReason is 'error' or 'aborted', as these cases already handle error output separately.
- This prevents duplicate error reporting in print mode when the assistant encounters terminal error conditions.

 ### Fixed
 
+- Fixed Anthropic tool schemas that used tuple-style arrays by stripping unsupported `maxItems` and only preserving provider-supported `minItems` values
 - Fixed Anthropic and OpenRouter Anthropic tool calls that previously failed with `compiled grammar is too large` by retrying automatically without strict tool schemas and reusing non-strict mode for subsequent requests in the same provider session
 - Fixed parsing of JSON tool arguments containing raw control characters inside string values (such as embedded newlines) by escaping them before JSON parsing
 - Fixed `validateToolArguments` to accept stringified objects and arrays that include literal control characters inside string fields
