Pivot persistent APIs to workspaces

Replace the public persistent-sandbox contract with workspace-first naming across CLI, SDK, MCP, payloads, and on-disk state.

Rename the task surface to workspace equivalents, switch create-time seeding to `seed_path`, and store records under `workspaces/<workspace_id>/workspace.json` without carrying legacy task aliases or migrating old local task state.

Keep `pyro run` and `vm_*` unchanged. Validation covered `uv lock`, focused public-contract/API/CLI/manager tests, `UV_CACHE_DIR=.uv-cache make check`, and `UV_CACHE_DIR=.uv-cache make dist-check`.
