docs: GET /api/workspaces/:id and GET /api/workspaces/current (GET) endpoints missing from behaviors.md

[evan-zhang11]

Documentation Gap

Two workspace GET endpoints are implemented but completely missing from behaviors.md:

1. GET /api/workspaces/:id (get_workspace)

Route: GET /api/workspaces/{id}
Auth: Required
Access control: User must be a member of the workspace
Response: 200 + {id, name, slug, ownerId, isPersonal, createdAt} / 401 / 403 (not a member) / 404 (not found or archived)
Handler: workspace_handlers.rs → get_workspace()

2. GET /api/workspaces/current (get_current_workspace)

Route: GET /api/workspaces/current
Auth: Required
Behavior: Returns the user's current active workspace. If currentWorkspaceId is set and valid, returns that workspace. Otherwise falls back to the first available workspace (personal first, then oldest).
Response: 200 + {id, name, slug, isPersonal} / 401 / 404 (no workspace found)
Handler: workspace_handlers.rs → get_current_workspace()

Note: WS-005 only documents PUT /api/workspaces/current (switch workspace). The GET method on the same path is a separate endpoint that is not documented.

Impact

• Workspace detail view and current workspace retrieval are P0 features
• Frontend depends on both endpoints for workspace management
• Missing documentation makes it hard to understand the workspace API surface

Suggested Fix

Add two new behavior contract entries:

• WS-011: GET /api/workspaces/:id — workspace detail retrieval
• WS-012: GET /api/workspaces/current — current workspace retrieval (companion to WS-005 switch)

Context

• Related to docs: POST /api/workspaces/:id/leave and GET /api/workspaces/archived missing from behaviors.md #371 (leave + archived endpoints missing) and docs: behaviors.md missing icon upload API and archived workspaces endpoint #222 (general missing endpoints)
