Walkthrough

Trigger handling now uses shared helpers to resolve configuration and select literal trigger text before the cursor. SmartblocksMenu resolves the current textarea, closes when no selection exists, and passes selected text and bounds to sbBomb. sbBomb accepts optional originalText. New tests cover selection order, literal characters, offsets, disabled triggers, and defaults.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 793ee

When a user types a trigger, the menu can close before the new character is reflected in the textarea, preventing workflow filtering and selection from updating correctly. This is a bounded correctness issue in the changed behavior and should be fixed before merging.

getTriggerSelection so menu visibility is based on whether a selection exists,
not whether selection.filter is non-empty; preserve an empty filter when a valid
