v0.3.0

Changes

• Introduce TraceReducer - incremental state machine that pairs LLM and eval events, groups sub-agent spans, and collapses redundant eval_and_complete + return/done pairs, replacing the previous multi-pass list processing in the Trace component
• Add system prompt overlay with agent config badges, accessible from the agent detail header
• Inline eval results directly into their parent LLM step instead of rendering separate rows
• Display final LLM response text and LLM errors in trace view
• Add ResetForm JS hook to clear chat input after submit
• Properly escape quoted strings when extracting HumanTool.ask questions
• Use Igniter module aliases in the install mix task
• Add tests for DashboardLive, TraceReducer error paths, and legion_web.install task
