docs(14.2.1): lock Go tables to golem15_translate_*

Execute-phase Task 2 chose golem15-prefix over the researched winter_translate_* names so the plugin ships vendor tables; PHP winter names stay a later import mapping.

 ### Model API
 - **D-09:** A Go model declares translatable attributes with a `Translatable() []string` (or equivalent tagged list) the way PHP uses `$translatable`. Journal copies the PHP Post/Category lists. — **Reversibility:** costly — every translatable model in shared plugins will call this.
-- **D-10:** Storage uses the same tables and columns as this PHP pin (`golem15_translate_*` attributes/indexes/locales — researcher confirms exact names from the frozen updates). No JSON-column alternative. — **Reversibility:** one-way — Winter import and Journal cutover expect those tables.
+- **D-10:** Go storage tables are `golem15_translate_locales`, `golem15_translate_attributes`, `golem15_translate_indexes`, and `golem15_translate_messages`, with the PHP pin's columns and indexes. No JSON-column alternative. PHP at SHA `725d547` uses `winter_translate_*`; do not copy those names into Go DDL. Winter import needs a later mapping. Locked at execute-phase Task 2 (2026-10-06) as `golem15-prefix`. — **Reversibility:** one-way — Journal and every host migrate against these names.
 - **D-11:** A missing translation falls back to the default locale, as PHP does.
 - **D-12:** The exported API other plugins call this phase is the minimum: `WithLocale` on queries, get/set an attribute in a locale, and current locale from Translator. Do not 1:1 every PHP `TranslatableModel` / `Translator` method name unless research shows Journal needs it.
 
 ### Where it boots
 - **D-13:** The host is `sm-grzybyfunkcjonalne-app` (same as Phase 15 D-18). This phase mounts `sm-user-plugin` + `sm-translate-plugin`; Journal is added in Phase 15. — **Reversibility:** one-way — submodule layout lands in that app.
 - **D-14:** Local app checkout: `/media/nvme/dev/golem15/summercms.io/summercms/sm-grzybyfunkcjonalne-app/` (sibling of `summercms.go`).
-- **D-15:** The user creates the public Gitea remote `git@git.golem15.com:golem15/sm-translate-plugin.git` as a manual plan step (it does not exist yet). Module path `git.golem15.com/golem15/sm-translate-plugin`, package `translate`, plugin ID `golem15.translate`.
+- **D-15:** The public Gitea remote is `git@git.golem15.com:golem15/sm-translate-plugin.git` (created 2026-10-06). Module path `git.golem15.com/golem15/sm-translate-plugin`, package `translate`, plugin ID `golem15.translate`.
 - **D-16:** Local plugin checkout: `/media/nvme/dev/golem15/summercms.io/summercms/sm-translate-plugin/` (sibling of `summercms.go`). The host mounts it as a submodule at `plugins/golem15/translate` with a `go.work` replace.
 - **D-17:** Phase proof: the app boots with user+translate; Locales admin works; a fixture model can save and read `en`+`pl` through ML fields and `WithLocale`.
 
 ### Claude's Discretion
-- Exact `golem15_translate_*` table/column names and migration IDs, taken from the frozen PHP updates (D-10), not invented.
+- Exact `golem15_translate_*` Go table names (D-10 execute lock); column/index shapes still come from the frozen PHP updates, not invented.
 - ML field YAML type names and SPA locale-switcher chrome, provided they follow cabana fail-loud rules and update the module README, `docs/`, admin OpenAPI, generated TS types and committed `dist/` in the same change.
 - How `mlmarkdown` shares implementation with Phase 15's markdown field (land the shared primitive here if Journal is otherwise blocked).
 - Plan count and split, subject to the plan-count checkpoint and "unit tests are the last plan".
