feat: port scheduler-docker-local :report subcommand to golang

The bash :report implementation for the scheduler-docker-local plugin is replaced with a compiled golang binary. The plugin already shipped golang code, so the report subcommand is added alongside its existing triggers binary, and the init-process and parallel-schedule-count helpers remain in bash for the deploy pipeline.
