## Changes
- Add `client/src/locales/it.json` — Italian translation of all 874 UI
keys, structure mirrors `en.json` exactly. Placeholders (`{{value}}`,
etc.) and inline tag tokens (`<settingsLink>`, `<highlight>`, ...)
are preserved. Product/brand names, technical abbreviations, and
placeholder-style examples (e.g. `you@example.com`) are kept in
English. 116 leaves are intentionally kept verbatim in English
(brand names, protocol names, sample values, port numbers, regex).
- Register `it: "Italiano"` in `LanguageSelector`'s `languageNames`
map so the dropdown shows the localised name; the selector already
picks up any locale present in the i18n resources.
- Fill in the two "How do I..." sections that CONTRIBUTING.md's table
of contents already links to but did not have bodies:
- "Improve the documentation?" — short guidance on doc PRs and
keeping README translations in sync.
- "Help with translations?" — describes the current per-language
JSON workflow (source of truth: `en.json`; improve an existing
language by editing its JSON; add a new one by adding a JSON file
and registering the display name in `LanguageSelector`). Notes
that the older PoEditor sync workflow is no longer authoritative.
## Benefits
- Italian speakers can now use Checkmate in Italian.
- Contributors who follow the "Help with translations?" link from
the CONTRIBUTING TOC land on real, current guidance instead of a
broken anchor.
- Translation quality can be improved incrementally by anyone
editing `it.json` directly; no external tooling required.
Replace the flag + 2-letter code in the language selector with each language's native name (English, Deutsch, 日本語, ...) and drop the unused flag-icons dependency.
