fix: feat: supervisor metrics logging for planner trend analysis (#24)

- supervisor-poll.sh: append structured JSONL metrics on every poll
  - infra metric (ram_used_pct, disk_used_pct, swap_mb) after Layer 1 checks
  - ci metric (pipeline id, duration_min, status) per project via wpdb query
  - dev metric (issues_in_backlog, issues_blocked, pr_open) per project via Codeberg API
  - rotate_metrics() trims metrics/supervisor-metrics.jsonl to last 30 days on startup
- planner-agent.sh: reads last 7 days of metrics before Phase 2 gap analysis
  - computes avg CI duration, success rate, RAM/disk utilization, blocked ratio
  - injects summary into gap analysis prompt as "Operational metrics" section
  - instructs planner to create optimization issues when metrics conflict with VISION.md
