restore missing opencode spec

+## Why
+- Windsurf exposes "Workflows" as the vehicle for slash-like automation: saved Markdown files under `.windsurf/workflows/` that Cascade discovers across the workspace (including subdirectories and up to the git root), then executes when a user types `/workflow-name`. These files can be team-authored, must stay under 12k characters, and can call other workflows, making them the natural place to publish OpenSpec guidance for Windsurf users.\
+  ([Windsurf Workflows documentation](https://docs.windsurf.com/windsurf/cascade/workflows))
+- The Wave 12 changelog reiterates that workflows are invoked via slash commands and that Windsurf stores them in `.windsurf/workflows`, so the OpenSpec CLI just needs to generate Markdown there to participate in Windsurf's command palette.\
+  ("Custom Workflows" section, [Windsurf changelog](https://windsurf.com/changelog))
+- OpenSpec already ships shared command bodies for proposal/apply/archive and uses markers so commands stay up to date. Extending the same templates to Windsurf keeps behaviour consistent with Claude, Cursor, and OpenCode without inventing new content flows.
+
+## What Changes
+- Add Windsurf to the CLI tool picker (`openspec init`) and the slash-command registry so selecting it scaffolds `.windsurf/workflows/openspec-proposal.md`, `openspec-apply.md`, and `openspec-archive.md` with marker-managed bodies.
+- Shape each Windsurf workflow with a short heading/description plus the existing OpenSpec guardrails/steps wrapped in markers, ensuring the total payload remains well below the 12,000 character limit.
+- Ensure `openspec update` refreshes existing Windsurf workflows (and only those that already exist) in-place, mirroring current behaviour for other editors.
+- Extend unit tests for init/update to cover Windsurf generation and updates, and update the README/tooling docs to advertise Windsurf support.
+
+## Impact
+- Specs: `cli-init`, `cli-update`
+- Code: `src/core/configurators/slash/*`, `src/core/templates/slash-command-templates.ts`, CLI prompts, README
+- Tests: init/update integration coverage for Windsurf workflows

+## MODIFIED Requirements
+### Requirement: AI Tool Configuration
+The command SHALL configure AI coding assistants with OpenSpec instructions using a marker system.
+#### Scenario: Prompting for AI tool selection
+- **WHEN** run interactively
+- **THEN** prompt the user with "Which AI tools do you use?" using a multi-select menu
+- **AND** list every available tool with a checkbox:
+  - Claude Code (creates or refreshes CLAUDE.md and slash commands)
+  - Cursor (creates or refreshes `.cursor/commands/*` slash commands)
+  - OpenCode (creates or refreshes `.opencode/command/openspec-*.md` slash commands)
+  - Windsurf (creates or refreshes `.windsurf/workflows/openspec-*.md` workflows)
+  - AGENTS.md standard (creates or refreshes AGENTS.md with OpenSpec markers)
+- **AND** show "(already configured)" beside tools whose managed files exist so users understand selections will refresh content
+- **AND** treat disabled tools as "coming soon" and keep them unselectable
+- **AND** allow confirming with Enter after selecting one or more tools
+
+### Requirement: Slash Command Configuration
+The init command SHALL generate slash command files for supported editors using shared templates.
+#### Scenario: Generating slash commands for Windsurf
+- **WHEN** the user selects Windsurf during initialization
+- **THEN** create `.windsurf/workflows/openspec-proposal.md`, `.windsurf/workflows/openspec-apply.md`, and `.windsurf/workflows/openspec-archive.md`
+- **AND** populate each file from shared templates (wrapped in OpenSpec markers) so workflow text matches other tools
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage

+## MODIFIED Requirements
+### Requirement: Slash Command Updates
+The update command SHALL refresh existing slash command files for configured tools without creating new ones.
+#### Scenario: Updating slash commands for Windsurf
+- **WHEN** `.windsurf/workflows/` contains `openspec-proposal.md`, `openspec-apply.md`, and `openspec-archive.md`
+- **THEN** refresh each file using shared templates wrapped in OpenSpec markers
+- **AND** ensure templates include instructions for the relevant workflow stage
+- **AND** skip creating missing files (the update command only refreshes what already exists)

+## 1. CLI wiring
+- [ ] 1.1 Add Windsurf to the selectable AI tools in `openspec init`, including "already configured" detection.
+- [ ] 1.2 Register a `WindsurfSlashCommandConfigurator` that writes workflows to `.windsurf/workflows/` and ensures the directory exists.
+- [ ] 1.3 Ensure `openspec update` pulls the Windsurf configurator when winds is selected and skips creation when files are absent.
+
+## 2. Workflow templates
+- [ ] 2.1 Reuse the shared proposal/apply/archive bodies, adding Windsurf-specific headings/description before the OpenSpec markers.
+- [ ] 2.2 Confirm generated Markdown (per file) stays comfortably under the 12k character ceiling noted in the Windsurf docs.
+
+## 3. Tests & safeguards
+- [ ] 3.1 Extend init tests to assert creation of `.windsurf/workflows/openspec-*.md` when Windsurf is chosen.
+- [ ] 3.2 Extend update tests to assert existing Windsurf workflows are refreshed and non-existent files are ignored.
+- [ ] 3.3 Add regression coverage for marker preservation inside Windsurf workflow files.
+
+## 4. Documentation
+- [ ] 4.1 Update README (and any user-facing docs) to list Windsurf under native slash/workflow integrations.
+- [ ] 4.2 Call out Windsurf workflow support in release notes or CHANGELOG if applicable.
