Compact agent logs by default, verbose with POC_AGENT_VERBOSE

Skip full prompt logging and truncate tool results in normal mode.
Logs now show: header, tool calls with one-line results, response
text. Set POC_AGENT_VERBOSE=1 for full prompts and results.

Makes agent logs scannable at a glance instead of walls of text.
