v0.2.1: redeploy_project post-start polling (30s timeout)

DSM starts containers asynchronously - start_project returns immediately
while containers are still initialising. Adds _wait_for_project_running:
polls SYNO.Docker.Project/list every 2s up to 30s after issuing start.
Reports RUNNING on success; emits a warning instead of failure on timeout
so callers can still verify with get_project_status.

Applies to all three redeploy paths (RUNNING, STOPPED, BUILD_FAILED).

Also bumps version 0.2.0 → 0.2.1 and adds CHANGELOG entry.
