//! Profile management.
//!
//! Profiles represent credential configurations for S3-compatible providers.
//!
//! # Architecture
//!
//! - [`Profile`]         — full internal record; never holds secrets.
//! - [`ProfileSummary`]  — IPC-safe view for list responses.
//! - [`ProfileDetail`]   — IPC-safe view for single-profile fetch.
//! - [`ProfileStore`]    — in-memory + disk-persisted aggregate.
//! - [`ProfileStoreHandle`] — `Arc<Mutex<ProfileStore>>` for Tauri managed state.
//!
//! # Aggregation order (list)
//!
//! 1. AWS-discovered profiles (`~/.aws/credentials` + `~/.aws/config`).
//! 2. Environment-variable synthetic profile (when `AWS_ACCESS_KEY_ID` is set).
//! 3. Manual profiles loaded from `profiles.json`.
//!
//! Dedup key: `(source, display_name)`. Manual profiles always win.
//!
//! # OCP contract
//!
//! - [`ProfileSource`] is open for new variants (`Sso`, `WebIdentity`, …)
//!   without touching existing arms.
//! - [`Profile`] is the backend record; [`ProfileSummary`] / [`ProfileDetail`]
//!   are the IPC views. Adding an IPC field only touches the view type.
//! - Secrets never touch [`Profile`] — keychain absorbs them at creation time.
