v0.12.0

Added

• Time-intelligence analytics, each mining real stage/close-date
  history from per-deal changelogs (20 tokens/deal; a >100-deal
  warning prints once):
  • metrics aging — days-in-current-stage bucketed
    (--buckets, default 30,60,90) with per-stage p50/p90 dwell
    baselines; flags deals past their stage's p90.
  • metrics slippage — expected_close_date pushes: count, net days
    slipped, original→current close date, serial offenders
    (--min-pushes).
  • metrics conversion-matrix — full stage-to-stage transition counts
    including backward edges and won/lost terminals (the flow graph the
    funnel collapses).
  • audit stage-skips — forward gate-skips and backward regressions
    with actor attribution (informational; always exits 0).
