fix(test): autoplan-dual-voice sandbox registers skills + assertions read real stream-json

Root cause of months of silent local failure: the sandbox copied skill dirs to
the repo root, but claude >= 2.x resolves slash commands strictly from
registered skills, so /autoplan short-circuited with 'Unknown command' (0
turns, ~1s) on every attempt. Install /autoplan + review skills at
project-level .claude/skills/ (same pattern as skill-routing-e2e).

Also: the transcript filter matched entry.type === 'tool_use', a shape that
never appears at the top level of raw stream-json, so assertions only ever saw
the final result text; filter on assistant/user events instead. Hang
protection accepts the Phase 1 review dispatch (Agent/Task tool call carrying
review instructions) as progress evidence, since full Phase 1 completion is
15+ min of subagent work. Budget raised to 10 min / 40 turns.

Invisible in CI: the file is in neither evals.yml nor evals-periodic.yml
matrices (coverage decision filed in TODOS.md).
