Separating diagnostic log output from stdout allows clean capture of emulated terminal output when running with -terminal -headless, without relying on line-level filtering at the consumer. Default behaviour is unchanged. The flag is a no-op when -no-log-stdout is also set, since that gate disables terminal logging entirely; this is noted in the help text.

Each bullet in the composed release-notes header now links to its associated upstream PR (scarybeasts#58, scarybeasts#59, scarybeasts#60) so the credit chain is visible on the release page. Bullets will come off the list as PRs merge upstream and the changes ship in upstream releases.

Hi there,
As promised, here's another PR for a small feature for when running beebjit headless.
Currently log output goes to stdout and mixes with emulator output. Added a
-log-stderrflag that works alongside thestandard logging behaviour: when set, logs go to stderr instead of stdout. Makes it easier for a harness to distinguish emulator output from logging. Ignored if
-no-log-stdoutis also set.Default behaviour is left unchanged, strictly an opt-in mechanism.
Branch up on my fork at acscpt/beebjit:pr/log-stderr.
Thanks again for beebjit!
