agents: deduplicate timestamps, plan expansion, rename agent

- Add compact_timestamp() to store — replaces 5 copies of
  format_datetime(now_epoch()).replace([':', '-', 'T'], "")
  Also fixes missing seconds (format_datetime only had HH:MM).

- Add ConsolidationPlan::to_agent_runs() — replaces identical
  plan-to-runs-list expansion in consolidate.rs and daemon.rs.

- Port job_rename_agent to use run_one_agent — eliminates manual
  prompt building, LLM call, report storage, and visit recording
  that duplicated the shared pipeline.

- Rename Confidence::weight()/value() to delta_weight()/gate_value()
  to clarify the distinction (delta metrics vs depth gating).
