feat(cli): suporte i18n completo — 42 locales, --lang flag, config lang get/set/list (#2285)

feat(cli): suporte i18n completo — 42 locales, --lang flag, config lang get/set/list

- 42 locale files in bin/cli/locales/ (en + pt-BR fully translated, 29 with common/program, 11 scaffolds)
- --lang <code> global flag for per-execution override
- config lang get/set/list subcommands
- Locale persistence via ~/.omniroute/.env
- Path traversal protection via regex validation in normalize()
- Script generate-locales.mjs for scaffolding new locales
- Unit tests for lang commands + normalization security

Integrated into release/v3.8.0

 - Every user-facing string goes through `t("module.key", vars)`.

-  must update both `en` and `pt-BR` catalogs.
+- Catalogs live in `bin/cli/locales/{locale}.json` (nested objects).
+  42 files ship out-of-the-box: `en`, `pt-BR`, and 40 additional locales.
+  11 locales are scaffold-only (empty `{}`); all keys fall back to `en` automatically.
+- Detection order: `--lang` flag → `OMNIROUTE_LANG` env → `LC_ALL` → `LC_MESSAGES` → `LANG` → `en`.
+- Locale persisted via `config lang set <code>` — saves `OMNIROUTE_LANG` to `~/.omniroute/.env`.
+- Missing keys return the key itself (no crash).
+- PRs that add new strings **must** update `en.json` and `pt-BR.json`.
+  Other locale files are best-effort; missing keys silently fall back to `en`.
+- `normalize()` in `i18n.mjs` validates locale codes via `/^[a-zA-Z0-9-]+$/` to
+  prevent path traversal — never pass raw filesystem paths.
+- Canonical locale list: `config/i18n.json` — source of truth used by both CLI and
+  dashboard i18n pipelines.
+
+### Adding a new locale file
+
+1. Add entry to `config/i18n.json` with `code`, `english`, `native`, `flag`.
+2. Run `node bin/cli/scripts/generate-locales.mjs` — creates `bin/cli/locales/{code}.json`.
+3. Fill in translations (or leave as `{}` for en-fallback scaffold).
+4. The pre-commit hook `check-cli-i18n` will verify all `t()` keys exist in `en.json`.

+## Locale selection
+
+The CLI displays text in the user's language. Detection order:
+
+1. `--lang <code>` flag on the command line
+2. `OMNIROUTE_LANG` environment variable
+3. System env: `LC_ALL` → `LC_MESSAGES` → `LANG`
+4. Fallback: `en`
+
+**Set permanently:**
+
+```bash
+omniroute config lang set pt-BR       # saves to ~/.omniroute/.env
+omniroute config lang list            # show all 42 available locales
+omniroute config lang get             # show currently active locale
+```
+
+**One-time override:**
+
+```bash
+omniroute --lang de providers list    # run in German, not persisted
+OMNIROUTE_LANG=ja omniroute status    # same effect via env
+```
+
+**Adding a new locale**: add entry to `config/i18n.json`, then run:
+
+```bash
+node bin/cli/scripts/generate-locales.mjs
+```
+
 ## Adding a new command
 
 1. Create `bin/cli/commands/your-command.mjs`
-2. Export `runYourCommand(argv, context)` (pre-1.1) or `registerYourCommand(program)` (post-1.1)
-3. Register in `bin/cli/index.mjs` (pre-1.1) or `bin/cli/program.mjs` (post-1.1)
-4. Add strings to both `locales/en.json` and `locales/pt-BR.json`
+2. Export `registerYourCommand(program)` following the Commander pattern
+3. Register in `bin/cli/commands/registry.mjs`
+4. Add strings to `locales/en.json` and `locales/pt-BR.json`
 5. Write test in `tests/unit/cli-your-command.test.ts`
 
 See `CONVENTIONS.md` for exit codes, flag naming, output format, and destructive-action rules.

+## CLI i18n
+
+The `omniroute` CLI has its own i18n layer separate from the Next.js dashboard.
+
+### How it works
+
+- Every user-facing string in CLI commands goes through `t("module.key", vars)` from `bin/cli/i18n.mjs`.
+- Catalogs are JSON files in `bin/cli/locales/` — 42 ship out-of-the-box.
+- Locale falls back to `en` for any missing key, so partial translations are valid.
+- The source of truth for available locales is `config/i18n.json` (shared with the dashboard).
+
+### Locale selection
+
+Detection order (first match wins):
+
+| Priority | Source                   | Example                                 |
+| -------- | ------------------------ | --------------------------------------- |
+| 1        | `--lang` flag            | `omniroute --lang de status`            |
+| 2        | `OMNIROUTE_LANG` env var | `OMNIROUTE_LANG=ja omniroute providers` |
+| 3        | `LC_ALL` system env      | auto-detected from terminal locale      |
+| 4        | `LC_MESSAGES` system env | auto-detected from terminal locale      |
+| 5        | `LANG` system env        | auto-detected from terminal locale      |
+| 6        | Fallback                 | `en`                                    |
+
+Locale codes with underscores (`pt_BR`) are normalized to hyphen form (`pt-BR`).
+Locale codes are validated against `/^[a-zA-Z0-9-]+$/` — path traversal is rejected.
+
+### Saving a language preference
+
+```bash
+# Set language and save to ~/.omniroute/.env (persists across sessions)
+omniroute config lang set pt-BR
+
+# View current language
+omniroute config lang get
+
+# List all 42 available languages
+omniroute config lang list
+
+# JSON output
+omniroute config lang list --output json
+```
+
+The saved preference is written atomically to `~/.omniroute/.env` and is loaded by the
+CLI bootstrap before any command runs.
+
+### One-time override
+
+```bash
+# Override for one command only (not persisted)
+omniroute --lang de providers list
+```
+
+Note: the `--lang` flag does NOT write to the env file — it only affects the current
+invocation. Use `config lang set` to persist.
+
+### Available locales
+
+42 locale files ship in `bin/cli/locales/`. Full translations: `en`, `pt-BR`.
+Scaffold-only (all keys fall back to `en`): `bn`, `gu`, `he`, `in`, `mr`, `ms`, `phi`, `sw`, `ta`, `te`, `ur`.
+All other 29 locales have `common` + `program` keys translated.
+
+### Adding a new CLI locale
+
+1. Add the locale entry to `config/i18n.json`.
+2. Run `node bin/cli/scripts/generate-locales.mjs` — creates the locale file.
+3. Translate the keys (or leave as `{}` for en-fallback scaffold).
+4. PRs must add strings to `en.json` and `pt-BR.json`; other files are best-effort.
+
