fix seen set pollution from agent tool calls

Browse source 
The CLI render command was marking keys as seen in the user's session
whenever POC_SESSION_ID was set. Agent processes inherit POC_SESSION_ID
(they need to read the conversation and seen set), so their tool calls
to poc-memory render were writing to the seen file as a side effect —
bypassing the dedup logic in surface_agent_cycle.

Fix: set POC_AGENT=1 at the start of cmd_run_agent (covers all agents,
not just surface), and guard the CLI render seen-marking on POC_AGENT
being absent. Agents can read the seen set but only surface_agent_cycle
should write to it.
