feat: add Gemini CLI, OpenCode, and Windsurf IDE integrations

Gemini CLI: platform adapter mapping 6 of 11 hooks, settings.json
deep-merge installer, GEMINI.md context injection.

OpenCode: plugin with tool.execute.after interceptor, bus events for
session lifecycle, claude_mem_search custom tool, AGENTS.md context.

Windsurf: platform adapter for tool_info envelope format, hooks.json
installer for 5 post-action hooks, .windsurf/rules context injection.
