summary: Implement remaining critical-path E2E coverage after the Panel harness: keep existing isolated Panel tests, add wheel/drag-capture regression coverage and a minimal single-Pod rewind PTY regression, preserve binary/env/tmp isolation, and validate with focused E2E plus packaging/build checks.

role_plan: Orchestrator creates a dedicated child worktree and delegates to a Coder Pod with write scope for `tests/e2e`, relevant TUI/runtime crates, root Cargo files if needed, and this Ticket record. Reviewer focus: no real LLM/provider calls, fixture isolation, opt-in production boundary, PTY path coverage, and no broad runtime/API drift.

note: Implementation accepted and worktree created, but Coder Pod spawn is blocked by current Orchestrator delegation scope: child launch validation requires readable workspace root `/home/hare/Projects/yoi`, which this Pod cannot re-delegate. Wait for Orchestrator restore/restart with appropriate delegation or explicit direct-implementation authorization.
