Bump opencode to v1.4.12

Reduces locale generation from 200+ to 16 targeted locales (major world
languages + Nordic + key European). Saves build time and image size.
Users can add more at runtime via locale-gen.

+### Shared machine setup (multiple users, single OS account)
+
+For machines where multiple users share one OS account (e.g. a common `garage` user), a separate compose file isolates each user's config and data using a `SIGNUM` variable.
+
+Each user creates their own directory and setup:
+
+```bash
+# Replace <signum> with your username/identifier
+mkdir -p ~/<signum>/opencode-devbox
+cd ~/<signum>/opencode-devbox
+
+# Copy the shared-machine compose and env files
+cp /path/to/opencode-devbox/docker-compose.shared.yml docker-compose.yml
+cp /path/to/opencode-devbox/.env.shared.example .env
+
+# Create per-user config directory
+mkdir -p ~/<signum>/.config/opencode
+
+# Edit .env with your signum, provider, keys, etc.
+vim .env
+
+# Start
+docker compose up -d
+docker compose exec -u developer devbox-<signum> opencode
+```
+
+Each user's container, config, and named volumes are fully isolated:
+- Container name: `devbox-<signum>` (no collisions)
+- Named volumes: prefixed with the project directory name (automatic per-user isolation)
+- Opencode config: `~/<signum>/.config/opencode/` (per-user settings, OMOS config, etc.)
+
+See `docker-compose.shared.yml` and `.env.shared.example` for the full configuration.
+
 ### Rebuilding the Image
 
 `docker compose run` and `docker compose up` use the existing image — they **do not rebuild** when you change the Dockerfile or build args (e.g. updating `OPENCODE_VERSION`). Rebuild explicitly:
