Subject: [PATCH] fix: support Agent tool for sub-agent visualization

The Agent tool (used by Claude Code's Task tool invocations) was not
being visualized as a sub-agent character in the Pixel Agents office.

Three changes in transcriptParser.ts:

1. Add 'Agent' to PERMISSION_EXEMPT_TOOLS so it does not trigger the
   false permission-wait heuristic while the sub-agent is running.

2. Add `case 'Agent':` before `case 'Task':` in formatToolStatus so
   the status string starts with "Subtask: <description>". The webview
   checks for this prefix to call addSubagent() and spawn a new pixel
   character linked to the parent agent.

3. Include 'Agent' in the subagentClear guard so the spawned character
   is correctly despawned when the Agent tool completes.
