Add Windsurf IDE support with slash commands (#113)

* docs(windsurf): propose workflow support

* restore missing opencode spec

* Add Windsurf IDE support with slash commands

* feat(windsurf): add Windsurf workflows support under .windsurf/workflows and simplify templates\n\n- Write workflows to .windsurf/workflows instead of .windsurf/commands\n- Remove YAML frontmatter; add concise intro before managed markers\n- Add init/update tests for Windsurf and marker preservation\n- List Windsurf in README native tools table\n- Normalize registry indentation

* chore(windsurf): remove optional intro content to simplify workflows\n\n- Drop intro hook and headings for Windsurf workflows\n- Keep OPENSPEC markers-only body for safe updates\n- Adjust tests to assert marker-managed content

* feat(windsurf): add required YAML frontmatter to workflows\n\n- Include description and auto_execution_mode: 3 for proposal/apply/archive\n- Keep content minimal; body remains marker-managed
