//! Normalize secret names to a store-friendly canonical form.
//!
//! Conventions:
//! - Lowercase all ASCII letters
//! - Keep `a-z`, `0-9`, `_`
//! - Map `-`, `.`, ` `, `/` → `_`
//! - Collapse repeated underscores, trim leading/trailing `_`
/// Convert a raw secret name (e.g. `TELEGRAM_BOT_TOKEN`) into canonical form
/// (`telegram_bot_token`).
///
/// The normalization itself lives in `greentic-secrets`
/// ([`greentic_secrets_lib::canonical_secret_name`]) — the single
/// ecosystem-wide definition shared by start/setup/deployer, so a producer and
/// a reader can never derive a name differently.
