Add official Gitea MCP server to base image

Install gitea-mcp v1.1.0 (Go binary from gitea.com/gitea/gitea-mcp)
using the same multi-arch pattern as gosu/fzf/bat. Provides 50+ MCP
tools for Gitea API — repos, issues, PRs, releases, branches, wiki,
and Actions.

Disabled by default in auto-generated opencode.json (requires
GITEA_ACCESS_TOKEN and GITEA_HOST to be useful). Users enable it by
setting those env vars in .env and flipping enabled to true in their
opencode.json.

Env vars forwarded into the container via docker-compose.yml and
docker-compose.shared.yml environment blocks. Same {env:VAR} pattern
as the GitHub MCP server.

Docs updated: README.md (new Gitea MCP section with setup steps),
DOCKER_HUB.md (tools list), CHANGELOG.md (v1.14.28b entry).

+## MemPalace — persistent AI memory
+
+The image includes [MemPalace](https://github.com/MemPalace/mempalace), a local-first AI memory system that stores conversation history verbatim and retrieves it via semantic search. Nothing leaves your machine.
+
+### Enabling persistence
+
+Uncomment the palace volume in `docker-compose.yml`:
+
+```yaml
+- devbox-palace:/home/developer/.mempalace
+```
+
+Without the volume, palace data lives in the container's writable layer and is lost on `--force-recreate`.
+
+### MCP integration with opencode
+
+Add mempalace as an MCP server in your `opencode.json` (inside `~/.config/opencode/`):
+
+```json
+{
+  "mcp": {
+    "mempalace": {
+      "type": "local",
+      "command": ["python3", "-m", "mempalace.mcp_server"]
+    }
+  }
+}
+```
+
+This gives opencode access to 29 MCP tools for searching memory, querying the knowledge graph, managing wings/rooms/drawers, and agent diaries.
+
+### Basic usage
+
+```bash
+# Mine project files into the palace
+mempalace mine /workspace
+
+# Mine conversation transcripts
+mempalace mine ~/.local/share/opencode/ --mode convos
+
+# Search memory
+mempalace search "why did we switch to eno1"
+
+# Load context for a new session
+mempalace wake-up
+```
+
+Each workspace gets its own isolated "wing" — memories never leak between projects.
+
+### Storage
+
+Two separate named volumes keep different data classes apart:
+
+- **Palace data** (`~/.mempalace/`): ChromaDB vectors, SQLite knowledge graph, drawers. This is your memory — back it up, treat it as precious. Persists via the `devbox-palace` named volume.
+- **Embedding model cache** (`~/.cache/chroma/`): ONNX model (~79 MB), downloaded automatically on first search. Disposable — blow it away and it re-downloads in ~4 seconds. Persists via the `devbox-chroma-cache` named volume so you don't re-download on every container recreation.
+- **No API keys required** for core functionality (local embeddings via ONNX).
+
+Both volumes are commented out by default in `docker-compose.yml` — uncomment to enable:
+
+```yaml
+- devbox-palace:/home/developer/.mempalace
+- devbox-chroma-cache:/home/developer/.cache/chroma
+```
+
+**Air-gapped environments:** pre-populate the `devbox-chroma-cache` volume with the `all-MiniLM-L6-v2/` model contents. The palace volume needs no pre-population.
+
+## Gitea MCP server
+
+The image includes the [official Gitea MCP server](https://gitea.com/gitea/gitea-mcp) (`gitea-mcp`), providing 50+ MCP tools for interacting with self-hosted Gitea instances — repositories, issues, pull requests, releases, branches, wiki, and Actions.
+
+### Setup
+
+1. Create a Personal Access Token on your Gitea instance (Settings → Applications → Generate Token, scopes: `repo`, `read:user`).
+
+2. Add to your `.env`:
+   ```env
+   GITEA_HOST=https://your-gitea-instance.example.com
+   GITEA_ACCESS_TOKEN=your_token_here
+   ```
+
+3. Enable the gitea MCP server in your `opencode.json`:
+   ```json
+   {
+     "mcp": {
+       "gitea": {
+         "type": "local",
+         "command": ["gitea-mcp", "-t", "stdio", "--host", "{env:GITEA_HOST}"],
+         "environment": {
+           "GITEA_ACCESS_TOKEN": "{env:GITEA_ACCESS_TOKEN}"
+         },
+         "enabled": true
+       }
+     }
+   }
+   ```
+
+The server is installed but disabled by default — it requires authentication to be useful.
+
 ## Shell defaults
 
 The image ships a baked `.bash_aliases` and `.inputrc` with quality-of-life defaults. On first container start they are copied from `/etc/skel-devbox/` into `/home/developer/` **only if the target file does not already exist** — so host bind-mounts and any version you've customized inside the container are never overwritten on upgrade.
