squad_state_health resolvedTeamDir reports the repo root, not the squad directory #2455

Found in the Claude Code end-to-end test for epic #2438 (fresh repo, dev build, 2026-11-10).

What happens: squad_state_health reports the team squad dir correctly (…/squad-e2e-arcade/.squad), but its metadata field resolvedTeamDir holds the repository root (…/squad-e2e-arcade). Scribe flagged it during the run: "the health metadata field resolvedTeamDir shows the repo root rather than .squad … the field name is confusing."

Why it matters: agents and tools reading the handshake can mistake the repo root for the squad directory.

Suggested fix: either return the squad directory in resolvedTeamDir, or rename the field to what it holds (for example resolvedTeamRoot) and document both fields.
