chore(release): 0.1.4

Removed unnecessary union wrapper for the `remote` argument, now using a direct string schema with optional flag and updated description.

+
+## Project Overview
+
+opencode-multi-model is a Bun/TypeScript project that provides multi-model tmux session management for AI coding assistants. It allows running multiple AI models simultaneously in isolated tmux windows with separate git worktrees.
+
+Available as three integration modes:
+- **OpenCode Plugin**: Loaded via `opencode.json` plugin array
+- **Standalone CLI**: Install globally and run `opencode-multi-model open <session> -m <models...>`
+- **Project Tool**: Import core functions from `"opencode-multi-model/core"` for project-level commands (used during development).
+
+Requires: tmux, git, opencode or kilo binary, Bun runtime.
+
+## Build, Lint, and Test Commands
+
+```bash
+# Install dependencies
+bun install
+
+# Build for production
+bun run build
+
+# Run tests
+bun test
+
+# Run tests with coverage (HTML report in ./coverage)
+bun run coverage
+# Run a specific test by name
+bun test --test-name-pattern "fails if session name is empty"
+
+# TypeScript type checking
+bun run typecheck
+
+# Lint with Biome
+bun run lint
+
+# Auto-fix lint issues
+bun run lint:fix
+
+# Format code with Biome
+bun run format
+
+# Full quality check
+bun run typecheck && bun run lint
+```
+
+## Code Style Guidelines
+
+### General
+
+- Use **TypeScript** with strict mode
+- Use **Bun** as the runtime and package manager
+- Use ESM modules (`"type": "module"` in package.json)
+- Use `node:` prefix for Node.js built-ins
+
+### Formatting (Biome)
+
+- **Indent**: 2 spaces (not tabs)
+- **Quote style**: Double quotes for JS strings
+- **Semicolons**: Required
+- Run `bun run format` to format files
+
+### TypeScript Conventions
+
+- Use `interface` for object shapes; avoid `type` aliases unless needed
+- Use explicit return types on exported functions
+- Avoid `any` when possible
+- Use `noUncheckedIndexedAccess: true` and `noImplicitOverride: true` in tsconfig
+- All types/interfaces go in `src/types.ts`
+
+### Naming Conventions
+
+- **Files**: kebab-case (`multi-model-open.ts`)
+- **Functions**: camelCase (`openMultiModel`)
+- **Types/Interfaces**: PascalCase (`MultiModelOptions`)
+- **Constants**: UPPER_SNAKE_CASE (e.g., `MAX_SUGGESTIONS`)
+
+### Imports
+
+- Use `import type` for type-only imports
+- Group imports: external packages, internal modules, types
+- Biome automatically organizes imports
+
+### Documentation
+
+- Use JSDoc for all exported functions
+- Include `@example`, `@param`, and `@returns` descriptions
+- Add inline comments for hard-to-understand code
+- Modify Readme.md, if implementation details have changed.
+
+### Error Handling
+
+- Return result objects (e.g., `MultiModelResult`, `CloseSessionResult`, `CleanupResult`) with `success: boolean`
+- Include descriptive error messages prefixed with `Error:`
+- Provide actionable error messages (e.g., suggest valid models on invalid model name)
+- Use `chalk` for colored terminal output (red for errors, dim for secondary info, bold for primary info)
+
+### Shell Commands
+
+- Use `Bun.$` template tag for shell commands
+- Always use `quiet().nothrow()` to capture output without throwing
+- Wrap command execution in `runCommand()` utility from `core/utils.ts`
+- Use `shellQuote()` for user-provided values in shell commands
+
+### Testing
+
+- Use `bun:test` framework
+- Mock `Bun.$` using the `mock()` function from `bun:test`
+- Use `spyOn()` for fs/os module mocking
+- Group tests with `describe()` blocks
+- Test file naming: `*.test.ts` in `tests/` directory

+
+### Git Branch and Tag Naming
+
+- Session branches: `opencode/<session-name>/<window-name>`
+- Archive tags: `archive/<branch-name>-<timestamp>` (created by close command)
+- Worktrees: `~/.local/share/opencode/multi-model/<session>/<window>/`
+
+### Common Pitfalls
+
+- Tmux session names use raw input; git branches/paths use sanitized names
+- Window names must be unique; collisions get numeric suffixes (e.g., `gpt-5-2`, `gpt-5-2-2`)
+- Window names are truncated to 24 characters to fit tmux limits
+- Worktree paths are checked for existence before creation to avoid conflicts
+- Archive tags preserve branch state before deletion for recovery

+The `cleanup` command performs the following steps:
+
+1. **Archive tag discovery**: Finds all git tags matching the pattern `archive/*`

+2. **Local tag deletion**: Deletes all archive tags from the local repository

+   - Pushes tag deletions to the remote repository
