fix: read subagent descriptions directly from parent transcript

Instead of timing-based correlation between terminal output and subagent
files, now reads the Task tool's description parameter directly from the
parent session's transcript. This provides 100% reliable mapping between
agent IDs and their short descriptions, fixing issues where multiple
agents spawned in quick succession would get the same window title.
