{.topic} in cli requires a package-qualified topic reference to generate
a valid x-r-help:pkg::topic URI. Bare {.topic AMR-options} produced a
malformed x-r-help:AMR-options URI (no package prefix).
Use the [display_text](pkg::topic) form throughout:
{.topic [AMR-options](AMR::AMR-options)}
{.topic [AMR-deprecated](AMR::AMR-deprecated)}
The hyphen in the topic name is fine as a URI string even though
AMR::AMR-options is not a valid R symbol expression.
The fallback handler in format_message() already handles the [text](uri)
form by extracting the display text, so plain-text output is unchanged.
