fix(tui): show hunt verdicts in tasks

[cyq1017]

Refs #2093

Problem

run_verifiers exposes the hunt verdict in its JSON output, but durable task summaries did not retain that verdict, so /task list could not show the requested verdict glyph.

Change

• attach verifier_verdict, hunt_verdict, and goal_status metadata to synchronous run_verifiers results
• persist task_updates.hunt_verdict on durable tasks and expose it through TaskSummary
• render a Verdict glyph column in /task list only when a listed task has a hunt verdict

Verification

• cargo fmt --all --check
• cargo test -p codewhale-tui task_list_ --locked
• cargo test -p codewhale-tui record_tool_metadata_updates --locked
• cargo test -p codewhale-tui run_verifiers_emits_hunt_verdict_mapping --locked
