harn-cli 0.8.0

//! Top-level clap definition for the `harn` CLI.
//!
//! Per-subcommand arg structs live in their own modules under
//! `crates/harn-cli/src/cli/`. The `Cli` and `Command` enum here only
//! reference types via `pub(crate) use ...` re-exports so external
//! consumers can keep using `crate::cli::TypeName` unchanged.
//!
//! Some variants of subcommand enums are reached only by destructuring
//! the parent (`SubCommand::Foo(args) => ...`) and are never referenced
//! by name from outside this module. Those types stay private to their
//! per-subcommand module and are accessed through their parent enum.

USAGE
    harn run script.harn
    harn run -e 'println(\"hello\")'
    harn run script.harn -- arg1 arg2   (script reads `argv` as list<string>)

CONCURRENCY
    Harn supports first-class concurrency primitives:
      - spawn { ... }         — launch a task, return a handle
      - parallel each LIST    — concurrent map
      - parallel settle LIST  — concurrent map, collect Ok/Err
      - parallel N            — N-way fan-out
      - with { max_concurrent: N }  — cap in-flight workers
      - channels, retry, select
    https://harnlang.com/concurrency.html

LLM THROTTLING
    Providers can be rate-limited via `rpm:` in harn.toml / providers.toml
    or via `HARN_RATE_LIMIT_<PROVIDER>=N`. Rate limits control throughput
    (RPM); `max_concurrent` on `parallel` caps simultaneous in-flight jobs.
