fix(OSQUERY-004): 2 review findings in process.cpp

[flamingo]

Closes 2 review findings in osquery/process/posix/process.cpp.

Draft — this is a starting point, not a finished change. The fix required judgment, so read it before trusting it.

#	Fix confidence	Finding	Location
1	🟢 90 high	std::cerr used for diagnostic output instead of LOG() macros in process.cpp	osquery/process/posix/process.cpp:195
2	🟢 90 high	std::cerr used for diagnostic output in launchTestPythonScript	osquery/process/posix/process.cpp:233

What changed — and what was deliberately left — is explained per finding as inline review comments on the lines each finding touched.

closing it unmerged is recorded as rejection. Both feed rule health, so
closing a wrong suggestion is useful rather than merely tidy.

🦩 🟠 std::cerr used for diagnostic output instead of LOG() macros in process.cpp

In launchExtension() (osquery/process/posix/process.cpp), replaced std::cerr << "Could not start extension process: " << exec_path << ", error: " << errno << std::endl; with LOG(ERROR) << "Could not start extension process: " << exec_path << ", error: " << errno;, matching the existing LOG(ERROR) style used in launchWorker(). No other logic changed.

🦩 🟠 std::cerr used for diagnostic output in launchTestPythonScript

In launchTestPythonScript() (osquery/process/posix/process.cpp), replaced std::cerr << "Could not start process at " << osquery_python_path << ", args: " << args << ", error: " << errno << std::endl; with LOG(ERROR) << "Could not start process at " << osquery_python_path << ", args: " << args << ", error: " << errno;. The <iostream> include was left in place since it is not strictly required to be removed by the finding and removing it would be a drive-by change beyond scope.
