Add OpenCode and Tidewave CLI support

- OpenCode: Open-source AI coding assistant (npm install -g opencode-ai)
  Supports multiple LLM providers including OpenAI, Anthropic, Gemini

- Tidewave: Elixir/Phoenix MCP server for AI-powered development
  Downloads binary from GitHub releases with ELF validation
  Enables runtime introspection, SQL queries, and code evaluation

Both tools are optional components in the interactive installer.
Tidewave is automatically skipped if Erlang is not selected.
