Split the chat message-rendering polish out of feat/webgl-ambient-background onto the ui-foundation base: - MessageList: agent-colored avatars/names, skill-context collapsing, jump-to- latest, contentVisibility virtualization - StreamingMessage / WorkGroup / WorkEntryRow: tool-call + reasoning rendering refinements - WelcomeScreen / AgentWelcome / MessageActions: refreshed empty/welcome states and per-message copy actions - agentColors: user-accent-aware color resolution Fold in the P1 contrast fix: agent avatars previously hardcoded white text on arbitrary agent colors (fails AA on light palette entries). A luminance-based readableTextColor() now picks black or white per background. DIVERGENCE (intentional, owned): the source branch interleaved the Azure Speech voice integration into ChatInput/ChatPanel (useVoiceInput, VoiceModeController, dictation + voice-mode buttons). That integration is deferred to the azure-speech-voice feature branch; this branch carries the voice-free chat. When voice lands it re-adds the input wiring here. AgentProfileSummary.accentColor is added as an optional field (the genesis/profile branch makes it authoritative). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
