Server-driven interaction prompt that displays "E - Talk" when near an interactable NPC. Decodes v4 nearby_interactions from snapshot, stores in GameState, renders via InteractionPrompt UI with fade animation. Extensible interface (get_interaction_target/get_selected_verb) for future radial verb menu (v0.2). - Protocol: decode nearby_interactions array with nested VerbOption structs, entity relationship/observation fields, tick_rate in GameTime - GameState: store/clear nearby_interactions per snapshot - SimBridge: test mode generates v4 format with structured verbs - InteractionPrompt: PanelContainer with fade in/out, polls GameState - Tests: 19 new test cases covering protocol, state, sim bridge, UI, encoding - Fixture assertions updated for v4 protocol version Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# hides when empty. No game logic — pure display layer.

# v0.1: Single-line "E - Talk" (first verb on nearest entity)

# v0.2: Will be replaced/extended with radial verb menu.
