//! This module manages workflow execution context, including variables,
//! template rendering, and data flow between tasks.
//!
//! ## Canonical Namespaces
//!
//! All data accessible inside `{{ }}` template expressions is organised into
//! well-defined, non-overlapping namespaces:
//!
//! | Namespace | Example | Description |
//! |-----------|---------|-------------|
//! | `parameters` | `{{ parameters.url }}` | Immutable workflow input parameters |
//! | `workflow` | `{{ workflow.counter }}` | Mutable workflow-scoped variables (set via `publish`) |
//! | `task` | `{{ task.fetch.result.data }}` | Completed task results keyed by task name |
//! | `config` | `{{ config.api_token }}` | Pack configuration values (read-only) |
//! | `keystore` | `{{ keystore.secret_key }}` | Encrypted secrets from the key store (read-only) |
//! | `item` | `{{ item }}` or `{{ item.name }}` | Current element in a `with_items` loop |
//! | `index` | `{{ index }}` | Zero-based iteration index in a `with_items` loop |
//! | `system` | `{{ system.workflow_start }}` | System-provided variables |
//!
//! ### Backward-compatible aliases
//!
//! The following aliases resolve to the same data as their canonical form and
//! are kept for backward compatibility with existing workflow definitions:
//!
//! - `vars` / `variables` → same as `workflow`
//! - `tasks` → same as `task`
//!
//! Bare variable names (e.g. `{{ my_var }}`) also resolve against the
//! `workflow` variable store as a last-resort fallback.
//!
//! ## Function-call expressions
//!
//! Templates support Orquesta-style function calls:
