What does this PR do?

Adds Korean (ko) to all four translated surfaces, following
src/ha_mcp/settings_ui/locales/README.md:

Surface File How
Settings UI catalog src/ha_mcp/settings_ui/locales/ko.json authored — 462 messages, 29 tool_groups, 88 tools (title + description)
Custom component custom_components/ha_mcp_tools/translations/ko.json authored — all 94 config / options / issues / selector / entity / common strings
Add-on (stable) homeassistant-addon/translations/ko.yaml generated by python scripts/generate_locales.py
Add-on (dev) homeassistant-addon-dev/translations/ko.yaml generated by python scripts/generate_locales.py

AGENTS.md § Translations now lists ko too, as pinned by
test_agents_md_lists_every_shipped_locale.

Both authored catalogs are complete rather than stubs, so the daily
locale-sync workflow has nothing to backfill here.

Translation notes

  • Terminology follows the Korean Home Assistant UI: 영역 (area), 라벨 (label),
    장면 (scene), 헬퍼 (helper), 구역 (zone), 통합 구성요소 (integration),
    애드온 (add-on).
  • Kept verbatim on purpose, so a reader can still type or find them:
    identifiers and tool names (ha_search, enable_tool_search,
    WebSocket, DISABLED_TOOLS), every {placeholder}, every number and
    range, and the option labels the settings form itself renders in English
    (e.g. "Local network" in common.connect_local_lan).
  • <code>/<strong>/data-panel-link markup and link multiplicity are
    preserved key by key.

Type of change

  • 🐛 Bug fix
  • ✨ New feature
  • 📚 Documentation
  • 🔧 Maintenance/refactor
  • 🧪 Tests only
  • 💥 Breaking change

Testing

  • I have tested these changes with a LLM agent
  • All automated tests pass (uv run pytest)
  • Code follows style guidelines (uv run ruff check)

Ran locally on Windows:

  • pytest tests/src/unit/test_locale_parity.py tests/src/unit/test_settings_ui_i18n.py tests/src/unit/test_translate_locales.py — 326 passed
  • same three files with LOCALE_COMPLETENESS_CHECKS=1 — 436 passed, so the
    gated completeness, tool_groups/tools exactness and 5% English-share
    checks are green ahead of the post-merge sync
  • pytest tests/src/unit/test_settings_ui_js_behavior.py with tests/js
    npm deps installed — 178 passed (TestAlreadyDecidedCopy renders the
    Korean policies.pending.already_decided sentence)
  • full pytest tests/src/unit — the only failures are three pre-existing
    symlink cases in test_custom_component_filesystem.py that fail on
    master on this machine too (Windows symlink semantics), untouched by
    this PR

No English source string changed, so no locale_source_baseline.json
regeneration is needed.

Checklist

  • I have updated documentation if needed

Summary by CodeRabbit

  • New Features
    • Added complete Korean localization for the HA-MCP settings interface, tools, setup flows, options, and add-on configuration.
    • Korean translations now cover server settings, security policies, backups, accessibility, tool descriptions, errors, status messages, and update guidance.
    • Added Korean help text describing automatic backup throttling and continued writes when captures are skipped.
    • Added Esperanto to the documented list of available locale codes.

Add Korean to all four translated surfaces, per
src/ha_mcp/settings_ui/locales/README.md:

- src/ha_mcp/settings_ui/locales/ko.json (authored): all 462 messages,
  29 tool groups and 88 tool titles/descriptions
- custom_components/ha_mcp_tools/translations/ko.json (authored): all 94
  config/options/issues/selector/common strings
- homeassistant-addon{,-dev}/translations/ko.yaml (generated by
  python scripts/generate_locales.py)

Also lists `ko` in AGENTS.md § Translations, as pinned by
test_agents_md_lists_every_shipped_locale.

Terminology follows the Korean Home Assistant UI (영역/라벨/장면/헬퍼/
구역/통합 구성요소). Identifiers, option labels the reader has to find
on screen (e.g. "Local network"), env var names, numbers and
{placeholders} are kept verbatim.

Tests: tests/src/unit/test_locale_parity.py,
test_settings_ui_i18n.py, test_translate_locales.py all pass, including
with LOCALE_COMPLETENESS_CHECKS=1; test_settings_ui_js_behavior.py
passes with tests/js dependencies installed.

📝 Walkthrough

Walkthrough

The change documents Esperanto as a shipped locale and adds Korean translations for the custom component, add-on configuration, and HA-MCP settings UI.

Changes

Localization updates

Layer / File(s) Summary
Locale registry and integration translations
AGENTS.md, custom_components/ha_mcp_tools/translations/ko.json
The locale list includes Esperanto. The custom component adds Korean translations for configuration flows, server options, issues, selectors, entities, and connection status.
Add-on configuration translations
homeassistant-addon-dev/translations/ko.yaml, homeassistant-addon/translations/ko.yaml
The development and production add-on catalogs add Korean labels and descriptions for backup, security, tool, YAML, filesystem, dashboard, snapshot, and TLS settings.
Settings UI translation catalog
src/ha_mcp/settings_ui/locales/ko.json
The settings UI adds Korean metadata, messages, tool-group labels, and MCP tool titles and descriptions.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to f597c

The Korean translation set is otherwise merge-ready, but the auto-backup help text may imply that snapshots are always captured even when throttling skips them, which could mislead users about backup coverage; merge is reasonable with explicit owner follow-up to correct this wording.

Reviewed the mechanical side of all four surfaces.

  • Key sets are byte-identical to English everywhere: 462 messages, 29
    tool_groups, 88 tools, 94 component keys. No missing keys, no orphans.
  • Zero {placeholder} mismatches, zero inline-markup or data-panel-link
    target/multiplicity divergences, and zero identifier or number losses
    against the English sources.
  • AGENTS.md § Translations updated as test_agents_md_lists_every_shipped_locale
    requires, with nothing else in that file touched.
  • No English source string changed, so no locale_source_baseline.json repin
    is owed — matching what the PR description says.
  • The two add-on YAMLs are generated projections and carry the correct headers
    and key namespaces (addon_stable.* / addon_dev.*);
    test_derived_catalogs_match_the_canonical_store is green.
  • policies.operators.exists_long is present. That is the key
    locales/README.md calls out as the one no enum-derived check asks for, so
    it is the one a new locale most easily ships without.

I also checked the LOCALE_COMPLETENESS_CHECKS=1 set statically, since PR CI
never runs it: 0.07% of settings messages text and 0.00% of the component
catalog are byte-identical to English, against the 5% and 15% ceilings, and
every one of the 88 tools carries both a title and a description. Nothing here
will turn locale-sync.yml red on merge, and the daily sync has nothing to
backfill.

Filling both authored catalogs completely rather than shipping stubs is the
part that makes this land clean. Thanks for that, and for keeping the
identifiers, ranges and {placeholder} forms verbatim throughout.
