Acceptance Criteria

• Board card shows session last-4 when present
• Click-to-copy yields the full resume command
• Status line shows the session last-4
• bin/task stamps session_id and provider on building

Expected Test Plan

• unit: model resume helpers
• component: board renders widget
• integration: bin/task stamps session
• e2e: tasks board widget present

Checks Run

• [unit] bin/rails test test/models/task_test.rb — session_id_last4 / resume_command (claude+codex) / resume_command_display / nil-safe / normalize keeps keys
• [component] bin/rails test test/controllers/tasks_controller_test.rb — board card shows last-4 + copy control carrying full resume command; none when absent
• [integration] bin/rails test test/lib/task_cli_test.rb — bin/task stamps session_id+provider on create and on move building (read-merge); none without session. Plus test/lib/statusline_test.rb
• [e2e] npx playwright test e2e/session_resume.spec.js — /tasks shows the last-4 + resume copy control
