pub fn emit_error(localized_msg: &str)Expand description
Emits a localised error message to stderr via the tracing subscriber.
ADR-0047 / BUG-12 v1.0.88: prior implementation also called eprintln!
which produced a SECOND stderr line (Error:/Erro: prefix) for the same
error, on top of the structured tracing::error! line. Operators and
log parsers observed duplicated stderr lines.
The tracing subscriber is configured for stderr at main.rs:115, so a
single tracing::error! call already produces the human-readable line.
Callers that want a plain stderr line without tracing (e.g. one-shot
scripts) should use eprintln! directly instead of this helper.
Centralises human-readable error output following Pattern 5 (output.rs is
the SOLE I/O point of the CLI).
