Three resilience and honesty fixes from the v0.2.8 review. Minor version bump because redeploy_project and system_prune return different strings. M-4: trigger_build_stream now converts every non-ReadTimeout httpx.HTTPError (ConnectError, ConnectTimeout, WriteError, RemoteProtocolError, ...) into a SynologyError with a clear message. Previously only ReadTimeout was handled; everything else propagated as a raw httpx exception. redeploy_project now tracks whether stop was actually issued and, when build_stream fails after a successful stop, tells the user the project is in STOPPED state and recommends start_project / retry rather than the misleading "use stop + start separately" workaround. M-5: _wait_for_project_running exits early on BUILD_FAILED / ERROR (new _TERMINAL_FAILURE_STATUSES frozenset). DSM signals these statuses within seconds of a failed image pull; the old polling loop kept waiting up to 5 minutes for RUNNING. redeploy_project now surfaces the terminal status with a BUILD_FAILED-specific hint to update_image_tag. M-6: system_prune preview now enumerates user-created networks that have no containers attached (excluding the three built-in networks bridge/host/none, which Docker never prunes). Previously the preview noted "Unused networks: (not counted)" even though SYNO.Docker.Utils/prune does delete them — users could lose networks they had not been warned about. Tests: - 2 new dsm_client tests: ConnectError and RemoteProtocolError both raise SynologyError, not raw httpx exceptions. - 2 new project tests: recovery hint after stop+build_stream failure (RUNNING case); old workaround retained for the STOPPED case where no stop was issued. - 3 new polling tests: BUILD_FAILED and ERROR each trigger early exit; redeploy_project surfaces BUILD_FAILED with update_image_tag hint. - 2 new system_prune preview tests: counts unused networks correctly, excludes built-ins; network-fetch failure is non-fatal. 245 tests pass. ruff check + ruff format clean.
