Release 0.1.0: MIT license, changelog, multi-arch Docker image without CLI builds

- LICENSE (MIT), CHANGELOG for 0.1.0, README overhaul
- docker-compose.release.yml pulling the registry image
- Dockerfile cross-compiles the server with cargo-zigbuild for amd64 and arm64;
  the terminal client is no longer built into the image
- Server, install script and settings point to a source install of the
  terminal client when no prebuilt binaries are available (/info: cli_builds)

+# Changelog
+
+All notable changes to CodeCraft. Versions follow [Semantic Versioning](https://semver.org/);
+until 1.0, minor versions may contain breaking changes.
+
+## [0.1.0] – 2026-11-09
+
+First public release.
+
+### Agents and chat
+
+- Agent loop with streaming, task lists, subagents (parallel and in the background, on other
+  models), skills, slash commands, `AGENTS.md` / `CLAUDE.md`, automatic context compaction.
+- Modes: **build**, **plan** (read-only) and **craft** (study a website, app, game or old
+  program and build your own version, with visual comparison, clean room or deep mode),
+  plus custom modes and subagents. Review loops per mode.
+- Tools: files, shell with background processes, web fetch and search, LSP diagnostics after
+  edits, OpenSCAD for 3D printing, Ghidra for old binaries, image generation (fal.ai), and an
+  interactive **browser** (click, type, run JavaScript, screenshots, console errors; private
+  network addresses are blocked).
+- MCP servers (stdio and Streamable HTTP, elicitation, tools loaded on demand).
+- Permissions per tool and per shell command pattern, modes *ask*, *auto*, *accept edits* and
+  *bypass*; permission cards with diffs; questions from agents and MCP servers.
+- Checkpoints and rewind, fork, regenerate, accept changes hunk by hunk, git worktrees per
+  session, reasoning effort per message, voice input, `@file` mentions, attachments.
+- Project memory (`.codecraft/memory.md`, written by the agent) and personal memory.
+- Hooks before and after tool calls, on prompts and at the end of a turn.
+
+### Models
+
+- Anthropic natively and every OpenAI-compatible API (Gemini, OpenRouter, opencode,
+  fal.ai, Ollama, vLLM, llama.cpp, LM Studio).
+- Prices per model, concurrency limits per host and model, monthly budgets.
+- **Model fallback** when a host is unreachable or a budget is used up.
+- **Provider status**: every 5 minutes each provider's model list is checked (no tokens).
+
+### Web app
+
+- Installable PWA with push notifications (permissions, questions, finished turns) and a
+  **share target**: text and links shared from other apps start a chat or go into a recent one.
+- Guided start screen, file manager with previews (PDF, Office, 3D models, images), web
+  terminal, image gallery, git panel.
+- **Command palette** (Ctrl/Cmd+K) and keyboard shortcuts; **prompt templates** with
+  placeholders (personal and global); sessions can be **pinned, archived and filed into
+  folders**, grouped by date or project.
+- Statistics: tokens, cache hits, time to first token, prefill and output speed and cost per
+  request; cost and tokens per day, an activity heatmap of the last 14 days, tables per model,
+  provider, mode, user and session. Optional **daily cost summary** as a push at 20:00.
+- 15 colour themes, each light and dark; English and German.
+- "What's new" after updates; admins see when a new release is available.
+
+### Automations and integrations
+
+- **Automations**: agents on a cron schedule from a Markdown job file, created by an agent,
+  from a **template** or by hand; **incoming webhooks** start them (shared secret or
+  Gitea/GitHub HMAC signature; the payload is passed to the agent).
+- **API tokens** with full or read-only scope.
+- **Prometheus metrics** at `/metrics` (own bearer token) and JSON logs
+  (`CODECRAFT_LOG_FORMAT=json`).
+- **Backups**: daily zip of database and config, keep 30, optional copy to any S3-compatible
+  bucket; download from the settings.
+
+### Terminal client
+
+- `codecraft`: a full-screen terminal client like Claude Code or opencode. The agent loop,
+  tools and history stay on your machine; models, modes, rules, skills and the theme come
+  from the server, which counts usage and costs. Also runs **without a server**: a guided
+  setup connects Anthropic, OpenAI, Gemini, OpenRouter, opencode or local servers (Ollama,
+  LM Studio, llama.cpp/vLLM, detected automatically).
+- No prebuilt binaries in this release: install it from source with
+  `cargo install --locked --git https://git.familie-zink.org/zink/codecraft codecraft-cli`.
+
+### Users and security
+
+- Local accounts (Argon2) and single sign-on via OpenID Connect; admins and users, private
+  folders per user, shared folders, read-only session sharing, audit log.
+- Shell commands of non-admin users run in a bubblewrap sandbox.
+- Multi-arch Docker image (amd64, arm64).
