AgentEngineSandboxCodeExecutor uses wrong JSON field names for stdout/stderr

[guanerdan]

Description

The AgentEngineSandboxCodeExecutor class has two field name mismatches that cause it to fail silently:

Bug 1: stdout/stderr field names

Location: agent_engine_sandbox_code_executor.py lines 138-140

Code expects	API returns
stdout	msg_out
stderr	msg_err

Result: CodeExecutionResult.stdout and stderr are always empty.

Bug 2: Input file field names

Location: agent_engine_sandbox_code_executor.py lines 113-119

Code sends	API expects
contents	content
mimeType	mime_type

Result: Input files are not readable in the sandbox, causing errors like pandas.errors.EmptyDataError: No columns to parse from file.

Environment

• google-adk version: 1.19.0
• Python version: 3.13
