Three live-verified MCP weaknesses (update run 2026-06-22):
- exec_in_container: SYNO.Docker.Container/exec does not exist on this DSM
firmware (code 103, like pause/unpause). Catch it and return a guiding
"not supported on this firmware" message instead of the raw DSM error;
the tool stays available for firmwares that do implement exec.
- redeploy_project: the failure hint suggested stop_project + start_project,
but start_project does not recreate on a new image (it restarts the old
one). Both failure hints now point back at redeploy_project and warn about
parallel pull_image lock contention (DSM 2101/2202).
- check_image_updates: docstring and output now state it only reflects DSM
digest drift on already-pulled tags and does NOT discover newer version
tags (use list_image_tags + release notes for that).
Tests updated accordingly; CHANGELOG + version bumped to 0.9.1.
