Tools now resolve with error messages in content blocks rather than
rejecting the promise. This matches the expected behavior where tools
always return a result, with errors indicated in the text content.
- read: Return error content for missing files
- edit: Return error content for missing files, text not found, multiple matches
- bash: Return error content for command failures, timeouts, and aborts
- All tools now include required details field in error results
