Feature: Multi-Workspace Support with Data Isolation and Quick Switching

[hoangsonww]

Problem

The tool currently assumes a single logical workspace/data context. Users monitoring multiple repositories/teams need separation and quick switching.

Proposal

Add Workspace Profiles with strict data isolation and fast context switching.

Scope

• Workspace entity with name, root path patterns, color/icon
• Data partitioning per workspace (sessions, agents, events, analytics)
• Workspace switcher in sidebar/header
• Cross-workspace aggregate dashboard (optional)

UX Requirements

• Last selected workspace persisted across restarts
• Clear visual indicator of active workspace
• Safe fallback if workspace is missing/renamed

Technical Notes

• Add workspace_id to key tables with indexed access paths
• Migration strategy for existing single-workspace data
• Optional workspace filters on all API endpoints

Acceptance Criteria

• User can create/edit/archive workspaces
• New events are attributed to the correct workspace
• Switching workspace updates all views consistently
• Existing data migrates to a default workspace automatically
• API supports both scoped and aggregate queries
