feat(desktop): add agent teams

[wesbillman]

Summary

Add Agent Teams — named groups of personas that can be batch-deployed to channels.

What's new

Backend (Rust/Tauri)

• TeamRecord type with id, name, description, persona_ids, timestamps
• managed_agents/teams.rs — JSON storage with sort and unit tests
• commands/teams.rs — full CRUD: list_teams, create_team, update_team, delete_team
• Wired into lib.rs invoke handler

Frontend — Agents Settings Page

• tauriTeams.ts API layer
• React Query hooks (useTeamsQuery, useCreateTeamMutation, etc.)
• TeamsSection.tsx — team cards with persona avatar pills, dropdown menu
• TeamDialog.tsx — create/edit dialog with persona multi-select checkboxes
• TeamDeleteDialog.tsx — confirmation dialog
• AddTeamToChannelDialog.tsx — deploy all team personas to a channel at once
• useTeamActions.ts — extracted hook to keep AgentsView under file size limit

Frontend — Add Agent Dialog (channel-level)

• AddChannelBotTeamsSection.tsx — team toggle chips in the "Add agents" dialog
• Click a team chip → all its personas get selected/deselected. One click, whole squad.

Architecture

• Teams are local-only (stored in Tauri app data as teams.json, same pattern as personas)
• A team is a named list of persona IDs
• "Deploy team to channel" reuses the existing createChannelManagedAgents batch flow
• No relay or backend server changes needed

Quality

• TypeScript: zero errors
• Biome lint/format: zero errors
• Rust cargo check + clippy: passes
• Unit tests: all pass (including 3 new team sort tests)
• File size limits: all pass
• No unwrap()/expect() in Rust, no any types in TypeScript
