Fixes for host metrics and collector mode

Changed

• Bundled certificates have been updated.

• Use system-specific operation name in messaging span names.

  When messaging.operation.name is present (e.g. Queue.add), it is used directly as the span name prefix: Queue.add (myQueue). When only the generic messaging.operation.type is available (e.g. send), the word "message" is added for clarity: send message (myQueue).

Fixed

• Continue reporting non-disk host metrics when a mount is frozen.

• Emit the appsignal.action_name attribute instead of appsignal.root_name when set_root_name is used in collector mode. The collector only reads the action name from appsignal.action_name, so root names set this way were previously ignored, falling back to the OpenTelemetry span name.

• Update the OpenTelemetry span name directly when set_name is used in collector mode, instead of setting the appsignal.name attribute. The collector uses the span name as-is, so names set this way were previously ignored.

• Emit the db.system.name and db.query.text semantic-convention attributes instead of appsignal.sql_body when set_sql_body is used in collector mode. This fixes SQL query sanitization when using the experimental collector mode.

• Fix host-metrics leaking zombie [timeout] processes in Alpine linux containers.

  Before this release AppSignal agent relied on a proper init process that reaps child processes killed by system timeout. Now the agent terminates and reaps unresponsive child processes in host-metrics collection and a subreaper is no longer required.

• Emit request parameters and headers using the attribute names the collector recognizes when in collector mode. set_params now emits appsignal.request.payload instead of appsignal.request.parameters, and set_header uses the http.request.header prefix instead of appsignal.request.headers. The collector and server do not recognize the previous names, so this sample data was previously dropped in collector mode.
