CLIP Text Encode and friends whose text widget is backed by a connected
input cannot have their text changed via the widget (execution reads the
linked input), so sending to them was a silent no-op.
- Registry: compute text_widget_connected capability from the widget's
backing input link state; has_text_widget drops to false when wired;
include the flag in the registration fingerprint so link changes
re-register the affected nodes
- Registry: hook link connect/disconnect (graph events on new litegraph,
onAfterChange fallback for classic) on root and subgraphs, plus
subgraph-created for future subgraphs
- applyWidgetUpdate: skip inject_text when the target widget is connected
and self-heal the registry instead of writing a value that is ignored
- Web UI: drop text_widget_connected nodes from prompt/embedding send
candidates; show a Mark as -> Send Prompt Target hint toast when no
candidates remain (new uiHelpers.workflow.noPromptTargets key, synced
to all locales; zh-CN/zh-TW translated)
- Extract shared resolveTextWidget() used by both the candidate-set
logic and the write path so the two cannot drift apart
- Tests: workflow registry connection-state registration, subgraph
handling, fingerprint re-registration, inject_text write/skip paths,
setup link-change hooks; uiHelpers candidate filtering and hint toast
