ci: resolve openvoicestream-agent from in-repo wheel + fix pre-existing lint

CI (and any checkout without the ../seeed-local-voice sibling) failed at
`uv sync` because tool.uv.sources pointed at an editable local path that
only exists on the device. Point it at the vendored torch-free wheel
(deploy/jetson/reachy/vendor/openvoicestream_agent-0.1.0-py3-none-any.whl)
so the project resolves on CI, fresh clones, and image builds; regenerate
uv.lock accordingly.

With sync working, ruff now runs and surfaced 4 pre-existing F401 unused
imports (proof_engine_e2e.py, e2e_slv_plugin_local.py) — removed.

Verified locally: `uv sync --extra dev` succeeds, `ruff check .` clean,
`pytest tests/` → 550 passed, 58 skipped.
