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

-# WezTerm Terminal Support
-
-## Summary
-
-Successfully added support for **WezTerm** terminal emulator to companion-teams, bringing the total number of supported terminals to **4**:
-
-- tmux (multiplexer)
-- Zellij (multiplexer)
-- iTerm2 (macOS)
-- **WezTerm** (cross-platform) ✨ NEW
-
-## Implementation Details
-
-### Files Created
-
-1. **`src/adapters/wezterm-adapter.ts`** (89 lines)
-   - Implements TerminalAdapter interface for WezTerm
-   - Uses `wezterm cli split-pane` for spawning panes
-   - Supports auto-layout: first pane splits left (30%), subsequent panes split bottom (50%)
-   - Pane ID prefix: `wezterm_%pane_id`
-
-2. **`src/adapters/wezterm-adapter.test.ts`** (157 lines)
-   - 17 test cases covering all adapter methods
-   - Tests detection, spawning, killing, isAlive, and setTitle
-
-### Files Modified
-
-1. **`src/adapters/terminal-registry.ts`**
-   - Imported WezTermAdapter
-   - Added to adapters array with proper priority order
-   - Updated documentation
-
-2. **`README.md`**
-   - Updated headline to mention WezTerm
-   - Added "Also works with WezTerm" note
-   - Added Option 4: WezTerm (installation and usage instructions)
-
-## Detection Priority Order
-
-The registry now detects terminals in this priority order:
-
-1. **tmux** - if `TMUX` env is set
-2. **Zellij** - if `ZELLIJ` env is set and not in tmux
-3. **iTerm2** - if `TERM_PROGRAM=iTerm.app` and not in tmux/zellij
-4. **WezTerm** - if `WEZTERM_PANE` env is set and not in tmux/zellij
-
-## How Easy Was This?
-
-**Extremely easy** thanks to the modular design!
-
-### What We Had to Do:
-
-1. ✅ Create adapter file implementing the same 5-method interface
-2. ✅ Create test file
-3. ✅ Add import statement to registry
-4. ✅ Add adapter to the array
-5. ✅ Update README documentation
-
-### What We Didn't Need to Change:
-
-- ❌ No changes to the core teams logic
-- ❌ No changes to messaging system
-- ❌ No changes to task management
-- ❌ No changes to the spawn_teammate tool
-- ❌ No changes to any other adapter
-
-### Code Statistics:
-
-- **New lines of code**: ~246 lines (adapter + tests)
-- **Modified lines**: ~20 lines (registry + README)
-- **Files added**: 2
-- **Files modified**: 2
-- **Time to implement**: ~20 minutes
-
-## Test Results
-
-All tests passing:
-
-```
-✓ src/adapters/wezterm-adapter.test.ts (17 tests)
-✓ All existing tests (still passing)
-```
-
-Total: **46 tests passing**, 0 failures
-
-## Key Features
-
-### WezTerm Adapter
-
-- ✅ CLI-based pane management (`wezterm cli split-pane`)
-- ✅ Auto-layout: left split for first pane (30%), bottom splits for subsequent (50%)
-- ✅ Environment variable filtering (only `COMPANION_*` prefixed)
-- ✅ Graceful error handling
-- ✅ Pane killing via Ctrl-C
-- ✅ Tab title setting
-
-## Cross-Platform Benefits
-
-WezTerm is cross-platform:
-
-- macOS ✅
-- Linux ✅
-- Windows ✅
-
-This means companion-teams now works out-of-the-box on **more platforms** without requiring multiplexers like tmux or Zellij.
-
-## Conclusion
-
-The modular design with the TerminalAdapter interface made adding support for WezTerm incredibly straightforward. The pattern of:
-
-1. Implement `detect()`, `spawn()`, `kill()`, `isAlive()`, `setTitle()`
-2. Add to registry
-3. Write tests
-
-...is clean, maintainable, and scalable. Adding future terminal support will be just as easy!
