History entries, sleep records and `worktree ps` rows carried a flattened
top-level `outcome`, copied under different gates and without the main agent's
clock. They now carry `mainAgent` (state, outcome, stateStartedAt), the type
the live row already persists and sends, and every copy site takes it with
`interrupted` through one function, `agentVerdictFields`.
- The accessor reads `mainAgent` then the legacy flag; the mobile mirror
matches it line for line.
- Sleep records admit `mainAgent` with `normalizeMainAgentStatusField`, so a
malformed value drops the field, never the record.
- Mobile dates a main agent that failed under live subagents by its own clock,
as desktop does, and its row equality compares `mainAgent`.
- The activity feed reads a history entry's own `mainAgent` instead of
rebuilding one; the sync key and history equality compare it.
