v0.15.0

Added

• Continuous automation primitives:
  • watch — anomaly poller built on the hygiene checks: emits only the
    findings that are NEW since the last run (a per-profile state),
    and exits 8 when new findings arm the gate (default: must-severity)
    so cron can branch — pdcli watch || notify. --peek reads without
    advancing state; --checks narrows the checks; --severity must|should|all
    arms the gate. A finding that clears and later re-trips fires again.
  • sync warehouse — incremental NDJSON export for a data warehouse.
    Appends only records changed since the last run, per entity, with
    independent high-water marks in manifest.json; the first run seeds a
    full export and --full rebuilds from scratch. --since overrides the
    start. Pull-based CDC captures creates/updates only — hard deletes are
    not surfaced (reconcile against a periodic full backup).

Changed

• Hoisted the shared --since parser (resolveSince) into
  src/lib/period.js so changes and sync warehouse share one
  implementation. No behavior change.
