fix(team): use manifest.v2 as canonical team cwd metadata source

[wwenrr]

Summary

• remove non-canonical team cwd metadata fallbacks in resolveTeamWorkingDirectoryFromMetadata
• resolve team working directory from manifest.v2.json only (plus OMX_TEAM_STATE_ROOT env override)
• add regression coverage proving manifest metadata wins even if config.json metadata points elsewhere

Why

Issue #1108 tracks seam-gap cleanup after the thin-adapter cutover. This PR addresses acceptance criterion: one canonical metadata source for team state-root / working-directory resolution.

Verification

• npm run build
• node --test dist/team/__tests__/api-interop.test.js dist/compat/__tests__/rust-runtime-compat.test.js

Closes #1108

CI failure is unrelated to your changes — it's a known flaky test in notify-fallback-watcher.test.js (Ralph debounce race condition, expected: 1, actual: 2). Your PR only touches api-interop.ts and compat tests.

Re-running CI.
