chore: rebrand companion-os to clanker-agent

- Rename all package names from companion-* to clanker-*
- Update npm scopes from @mariozechner to @harivansh-afk
- Rename config directories .companion -> .clanker
- Rename environment variables COMPANION_* -> CLANKER_*
- Update all documentation, README files, and install scripts
- Rename package directories (companion-channels, companion-grind, companion-teams)
- Update GitHub URLs to harivansh-afk/clanker-agent
- Preserve full git history from companion-cloud monorepo

Companion is a minimal terminal coding harness. Adapt companion to your workflows, not the other way around, without having to fork and modify companion internals. Extend it with TypeScript [Extensions](#extensions), [Skills](#skills), [Prompt Templates](#prompt-templates), and [Themes](#themes). Put your extensions, skills, prompt templates, and themes in [Companion Packages](#companion-packages) and share them with others via npm or git.

Companion runs in four modes: interactive, print or JSON, RPC for process integration, and an SDK for embedding in your own apps. See [openclaw/openclaw](https://github.com/openclaw/openclaw) for a real-world SDK integration.

```bash
npm install -g @mariozechner/companion-coding-agent
npm install -g @mariozechner/clanker-coding-agent
```
Authenticate with an API key:
```bash
export ANTHROPIC_API_KEY=sk-ant-...
companion
clanker
```
Or use your existing subscription:
```bash
companion
clanker
/login # Then select provider
```
Then just talk to companion. By default, companion gives the model four tools: `read`, `write`, `edit`, and `bash`. The model uses these to fulfill your requests. Add capabilities via [skills](#skills), [prompt templates](#prompt-templates), [extensions](#extensions), or [companion packages](#companion-packages).

## Philosophy
Companion is aggressively extensible so it doesn't have to dictate your workflow. Features that other tools bake in can be built with [extensions](#extensions), [skills](#skills), or installed from third-party [companion packages](#companion-packages). This keeps the core minimal while letting you shape companion to fit how you work.

This keeps the core minimal while letting you shape clanker to fit how you work.
**No MCP.** Build CLI tools with READMEs (see [Skills](#skills)), or build an extension that adds MCP support. [Why?](https://mariozechner.at/posts/2025-11-02-what-if-you-dont-need-mcp/)
**No sub-agents.** There's many ways to do this. Spawn companion instances via tmux, or build your own with [extensions](#extensions), or install a package that does it your way.
