//! ritalin -- executive function for AI coding agents.
//!
//! Like Ritalin for ADHD: agents are smart but unfocused. They skip research,
//! hallucinate patterns, use stale training data, lose scope, and claim "done"
//! at 80%. This CLI helps them focus their intelligence on the right things.
//!
//! Built on the agent-cli-framework patterns:
//!   - JSON envelope on stdout, coloured table on TTY
//!   - Semantic exit codes (0-4)
//!   - `agent-info` for machine-readable capability discovery
//!   - `skill install` to register with Claude Code, Codex, Gemini
//!
//! The binary stays lean. The SKILL.md teaches reasoning. The gate enforces:
//!   - `init` creates a scope contract
//!   - `add` records obligations (research, reference, freshness, tests, etc.)
//!   - `prove` runs verification commands and records evidence
//!   - `gate` is the Stop hook — blocks until every critical obligation is discharged
