Subagent telemetry now tracks when a subagent is 'vetoed' under a specific prompt

What

Claude Code's subagent tracking now includes a recordVeto method and an isVetoedUnder check, backed by a new map that records whether a given subagent was vetoed under a particular prompt. This data is cleared along with the rest of a subagent's telemetry when it's cleaned up.

Why

This lets Claude Code keep track of veto decisions tied to specific prompts for subagents, though the finding doesn't specify what triggers a veto or how it affects subagent behavior.
