Findings cards

The agent's verification report and any bugs it finds get their own cards at the end of the run — separate from the step-by-step timeline.

The Result card holds the narrative summary (PASS / FAIL + steps the agent took). The Findings card lists every ## Bug / ## Minor / ## Note the agent flagged, severity-coloured.

Hover's system prompt teaches the agent to emit this structured block at the end of every run, so QA reading the saved spec can scan the bug list without scrolling through tool calls.
