Plugin System

Built-in assertion plugins available in ASSERTS. For writing your own — drop a .rhai file into ~/.grpctestify/plugins or ./.grpctestify/plugins, no flag needed — see:

Custom assertion plugins — .rhai scripts, one file can define many, naming/arity/private fn/sandboxing
Installing from a git host — grpctestify plugins install github.com/owner/repo, versioning, lockfile
Reporter plugins — on_test_start/on_test_end/on_suite_end hooks
Script stdlib — the native helpers (log_*, is_uuid, regex_match, ...) every script gets for free
