v0.6.6

[0.6.6] - 2026-08-29

Fixed

• nohup_stop now waits up to 15 seconds for the supervisor process to exit
  and up to 10 seconds for supervisor.lock to be released before proceeding.
  Previously, the 2-second deadline was too short on loaded CI runners:
  acquire_supervisor_lock in a freshly spawned supervisor could find a stale
  lock left by a supervisor still stopping its children, causing a false
  "supervisor already running" error and a failed wait_livez health check.

Added

• tests/gateway_unit.py: 9 direct unit tests for bin/apx-gateway pure
  functions — _percentile, _window_seconds, _bucket_seconds,
  _bounded_int, _cost_estimate, _redact_headers, _redact_json_value,
  _redact_secrets_in_text, and _scrub_url_path.
• tests/lifecycle.sh: 6 new subcommand assertions — apx doctor (security
  posture, durable metrics, and commands sections), apx chain get and
  apx chain clear, apx target get and apx target reset, and
  apx completions bash / apx completions fish structural checks.
• tests/dashboard.sh: 6 new API endpoint assertions — /api/history
  (durable flag and fixture row fields), model and status filters,
  /api/history/export.csv (headers and row content),
  /api/metrics/chains (per-chain fields and observational regression),
  and /api/metrics/sessions (session grouping and token totals).
