1//! # Languages Effect (CreateEffectForRequest)
2//!
3//! Effect constructor for the `Languages.GetAll` RPC method. Aggregates
4//! language contribution metadata from all scanned extensions (from
5//! `ApplicationState.Extension.ScannedExtensions`) and merges duplicate
6//! language IDs by unioning their aliases, extensions, filenames, filename
7//! patterns, and mimetypes. The result is returned as a flat JSON array
8//! matching the shape expected by Cocoon's `languages.getAll` API.
9//!
10//! ## Aggregation behavior
11//!
12//! - Each extension's `contributes.languages` array is scanned.
13//! - Languages with the same `id` are merged (first-wins for `configuration`).
14//! - Array fields (aliases, extensions, filenames, filenamePatterns, mimetypes)
15//!   are deduplicated across all contributing extensions.
