Backend/runtime authoritative worker list is now surfaced in the TUI.

Completed scope:

• Added backend runtime worker list DTO/API to the client crate.
• Added yoi workers and Backend runtime picker launch routing.
• Added client-side Backend URL resolution from explicit --backend or $XDG_CONFIG_HOME/yoi/client.toml, with workspace id read from explicit --workspace-id or <workspace>/.yoi/workspace.toml.
• Added TUI Backend worker picker using Backend WorkerSummary as authority and displaying runtime id, worker id, label/profile, state, and working-directory summary.
• Fixed missing GET routes for runtime worker list endpoints.
• Aligned the Backend worker picker styling/controls with the existing inline resume picker.
• Fixed the nix develop shell hook syntax error in devshell.nix.

Validation performed under nix develop included targeted cargo check/test/fmt and git diff --check. Manual TUI verification was also reported successful by the user.
