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.

+## Project overview
+
+Docker image packaging [opencode](https://opencode.ai) into a production-ready dev container. Two image variants (base and omos) are published to Docker Hub via Gitea Actions CI. Not a library or application — this is infrastructure (Dockerfile, entrypoint scripts, docker-compose, documentation).
+
+## File roles
+
+- `Dockerfile` — single multi-stage build for both variants. OMOS variant is controlled by `INSTALL_OMOS=true` build arg. All GitHub-sourced binaries are pinned with version ARGs.
+- `entrypoint.sh` — runs as root: UID/GID adjustment, SSH permissions, volume ownership fixes. Then drops to developer via gosu.
+- `entrypoint-user.sh` — runs as developer: git config, opencode.json generation from env vars, OMOS setup.
+- `DOCKER_HUB.md` — pushed to Docker Hub description via CI API call. Must stay under 25KB. Short description field must be ≤100 bytes.
+- `README.md` — source repo documentation. Must stay in sync with DOCKER_HUB.md (both describe the same features but for different audiences).
+- `.gitea/workflows/docker-publish.yml` — CI pipeline: three parallel jobs (build-base, build-omos, update-description). Triggered by tag push only.
+
+## Versioning scheme
+
+Tags follow `v{opencode_version}{letter}` — e.g. `v1.4.3k`. The number matches the opencode npm version. The letter suffix increments for container-level changes (tooling, docs, CVE fixes) on the same opencode version. CI produces four Docker Hub tags per release: `vX.Y.Zn`, `latest`, `vX.Y.Zn-omos`, `latest-omos`.
+
+## Critical conventions
+
+- **entrypoint.sh volume ownership loop** — when adding a new named volume mount point, add it to the `for dir in ...` loop in `entrypoint.sh` so root-owned volumes get chowned on startup.
+- **Three docs to keep in sync** — Dockerfile changes that add tools or features must be reflected in `README.md`, `DOCKER_HUB.md`, and `.env.example`. The docker-compose examples in both docs must match the source `docker-compose.yml` pattern.
+- **GitHub-sourced binaries** — fzf, gosu, git-lfs, neovim, bat, eza, zoxide, uv, rustup are installed from upstream releases (not apt) with pinned versions. Use the same `ARCH` case-switch pattern for multi-arch support (amd64/arm64).
+- **Shell scripts use `set -euo pipefail`** — both entrypoints are strict. Errors in volume chown or SSH permission operations are intentionally suppressed with `|| true`.
+- **Docker Hub description update** — uses `/v2/auth/token` endpoint (not the deprecated `/v2/users/login`). Auth uses `identifier`/`secret` fields, returns `access_token`, sent as `Bearer`. Short description must be ≤100 bytes.
+
+## CI quirks
+
+- Both build jobs include an IPv4 preference step (`gai.conf` + `driver-opts: network=host` for buildx) to work around intermittent IPv6 failures on the Gitea runners.
+- `update-description` job runs only when both builds succeed (`needs: [build-base, build-omos]`).
+- Tags must be pushed to trigger CI. Pushing to `main` alone does not build images.
+
+## Testing changes
+
+No test suite. Verify by:
+1. Building locally: `docker compose build`
+2. Running: `docker compose run --rm devbox bash`
+3. Checking tool availability inside container: `nvim --version`, `bat --version`, `uv --version`, etc.
+4. For entrypoint changes: test with a non-1000 UID workspace to verify UID adjustment and volume ownership fixes.
+
+## Commit style
+
+Imperative mood, first line summarizes the change. Multi-line body explains "why" when non-obvious. Examples from history:
+- `Fix ownership of named volume mount points in entrypoint`
+- `Add uv package manager to base image for on-demand Python support`
+- `Upgrade base image from Debian bookworm to trixie (current stable)`

-## Initial Setup
+### Locale and Editor
 
-### 1. Create a project directory
+The container defaults to English (`en_US.UTF-8`) and neovim as the editor. Override via environment variables:
+
+| Variable | Description | Default |
+|---|---|---|
+| `LANG` | System locale | `en_US.UTF-8` |
+| `LANGUAGE` | Language priority list | `en_US:en` |
+| `LC_ALL` | Override all locale settings | `en_US.UTF-8` |
+| `EDITOR` | Default text editor | `nvim` |
+
+Pre-generated locales: `en_US`, `en_GB`, `sv_SE`, `da_DK`, `nb_NO`, `fi_FI`, `de_DE`, `fr_FR`, `es_ES`, `it_IT`, `pt_BR`, `nl_NL`, `pl_PL`, `ja_JP`, `ko_KR`, `zh_CN` (all UTF-8).
+
+Example for Swedish:
 
 ```bash
+LANG=sv_SE.UTF-8
+LANGUAGE=sv_SE:sv
+LC_ALL=sv_SE.UTF-8
+```
+
+To add a locale not in the list, run inside the container:
+
+```bash
+sudo sed -i '/xx_XX.UTF-8/s/^# //g' /etc/locale.gen
+sudo locale-gen
+```
+
+Replace `xx_XX` with the desired locale (e.g. `ru_RU`, `tr_TR`). This change does not persist across container restarts — for permanent additions, build from source and modify the Dockerfile.
+
+## Initial Setup
+
+### 1. Create host directories
+
+Bind-mounted directories must exist on the host before starting the container. Docker creates missing directories as root-owned, which causes permission issues.
+
+```bash
+# Required
 mkdir -p ~/projects
+
+# If mounting opencode config (recommended for persistent settings)
+mkdir -p ~/.config/opencode
+
+# If using AWS Bedrock
+# mkdir -p ~/.aws
+
+# If mounting neovim config
+# mkdir -p ~/.config/nvim

+2. Start the container: `docker compose up -d`
+3. In VS Code: `Ctrl+Shift+P` → "Dev Containers: Attach to Running Container" → select `opencode-devbox`

+
+```yaml
+volumes:
+  - devbox-vscode:/home/developer/.vscode-server
+```
+
+### 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.

+#
+# Setup per user:
+#   1. mkdir -p ~/<signum>/opencode-devbox && cd ~/<signum>/opencode-devbox
+#   2. cp docker-compose.shared.yml docker-compose.yml
+#   3. cp .env.shared.example .env
+#   4. Edit .env with your signum, provider, keys, etc.
+#   5. mkdir -p ~/<signum>/.config/opencode
+#   6. docker compose up -d

+# Named volumes are automatically isolated per user because Docker Compose
+# prefixes them with the project directory name (e.g. opencode-devbox_devbox-data).
+# Since each user runs from ~/<signum>/opencode-devbox/, volumes don't collide.
