antsibull-changelog imports ansible-core, which refuses to start if any of stdin/stdout/stderr is non-blocking. Confirmed live in run #13: the Forgejo Actions docker-exec environment hands the job non-blocking stdio, so both antsibull-changelog calls failed with a generic "ERROR: Uncaught exception" and no useful message.

Fix: clear O_NONBLOCK on all three fds via a short python3 snippet before the antsibull-changelog calls. Verified locally by running the exact script as a single bash -c invocation (matching how a run: | step actually executes): fails without the fix, exits 0 with it.

antsibull-changelog imports ansible-core, which refuses to start if any
of stdin/stdout/stderr is non-blocking. Confirmed live in run #13: the
Forgejo Actions docker-exec environment hands the job non-blocking
stdio, so both antsibull-changelog calls failed with a generic
"ERROR: Uncaught exception" and no useful message (only visible with
-v, which isn't passed). Clearing O_NONBLOCK on all three fds via a
short python3 snippet before the antsibull-changelog calls fixes it --
verified locally by running the exact same script as a single bash -c
invocation (matching how a `run: |` step actually executes): fails
without the fix, exits 0 with it.
