feat(kvb-coach): run the short coach at the first prompt of every full hour

hooks/reminder.sh claims the current clock hour with an atomic mkdir under ~/.claude/.coach-hours/, so only the first prompt of the hour across all agents gets the COACH HOUR hint (at most three lines, most urgent area first, then the request); earlier hours are removed. enable-plugins.js registers it next to the kvb-dream reminder. test_coach covers once per hour, silence within the hour and the cleanup; test_dream checks the single registration. Operator order 2026-11-03.

-Both commands also patch the target's `.claude/settings.local.json` — the machine-local, untracked file, so a project's reviewed `.claude/settings.json` is never rewritten by an install: the caveman and ponytail plugins are enabled so their modes auto-activate on session start, and one reminder hook is registered — `kvb-dream` points each agent at `/kvb-dream` at most once every twelve hours (stamped per session in `~/.claude/.dream-stamps/`); the global install also enables the `kvb-dream-notify.timer` systemd user timer, which recommends `/kvb-dream` in a GNOME notification daily at 17:00 local time and catches up once after a missed run. A PreToolUse gate from the `kvb-org-organize` skill blocks edits to files in a git worktree until the session holds a claim (`skills/kvb-org-organize/scripts/council.py`), and its resource watch (`skills/kvb-org-organize/scripts/watch.py`) measures disk, Docker and caches, cleans up low-risk data and blocks new heavy jobs before the disk runs out; it stays inactive until `~/.config/agents-council/config.json` exists. Two hooks of the `kvb-org-perform` skill (`skills/kvb-org-perform/scripts/log.py`) log every Agent spawn with its task class, model and effort, and store the quality feedback a sandboxed session prints, in `~/.local/state/agents-council/subagent-model.jsonl`. Existing settings are preserved.

 Restart your agent afterwards so it loads the new skills.
