fix(i18n): preserve hierarchy so Crowdin sync targets the existing source file

[feruzm]

Problem

The Crowdin upload/download workflows run the CLI without preserve_hierarchy, so the source path src/config/locales/en-US.json gets flattened to <branch>/en-US.json. Because the project's real, fully-translated source file lives at development/src/config/locales/en-US.json, the flattened upload didn't update it — it forked a second, empty copy of every string.

Crowdin then counted both copies, so the project reported roughly half its true translation progress, and a download in that state could have pulled the empty copy over the translated locale files.

Fix

Set preserve_hierarchy: true in crowdin.yml so both upload and download keep the repo path under the branch and resolve the existing source file. One line; no workflow changes needed (the action reads this config).

The Crowdin side has been reconciled separately (duplicate file removed, source re-synced); after this merges, a normal sync-translations run will batch the up-to-date translations back into the repo.

Greptile Summary

This PR adds preserve_hierarchy: true to crowdin.yml so the Crowdin CLI keeps the full repository path (development/src/config/locales/en-US.json) when resolving files, instead of flattening it to <branch>/en-US.json and inadvertently forking a second untranslated copy.

• Adds a single preserve_hierarchy: true line to crowdin.yml with explanatory comments; no workflow changes are needed since crowdin/github-action@v2 reads this config automatically.
• Both the upload (crowdin-upload.yml) and download (crowdin-download.yml) workflows already specify crowdin_branch_name: development, so they will correctly resolve to the fully-translated source file once this setting is in place.

Confidence Score: 5/5

Safe to merge — the change is a single well-understood Crowdin config flag with no runtime code impact.

The change is one line in a YAML config file. The flag is the standard Crowdin mechanism for preserving directory structure, the workflows already supply the correct crowdin_branch_name, and the PR description confirms the Crowdin-side reconciliation has been done. There is no logic to break and no ambiguity in how the option behaves.

No files require special attention.

Important Files Changed

Filename	Overview
crowdin.yml	Adds preserve_hierarchy: true so the Crowdin CLI maps the source file to development/src/config/locales/en-US.json instead of flattening it to development/en-US.json, preventing duplicate file creation on Crowdin.
