feat(check): security value, commit tables, MEDUSA install and kvb-think-choice

kvb-check-security gains security.py: it scans the changed files with MEDUSA, weights findings (critical -50, high -25, medium -10, low -2) and prints locations and counts only; without MEDUSA it asks for a review by hand passed as '~<n>'. kvb-check-score takes --security and --critical: the score multiplies by security/100, a critical finding blocks the commit (exit 4), security below 100 asks the operator like efficiency or speed over 100, and a 90/5 failure now lists every cause. --table and --commit-table print the values as markdown tables, shown before and after every commit.

make install installs MEDUSA with pipx unless it is on the PATH. The new kvb-think-choice skill offers open decisions as multiple choice and checkboxes.

-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 two reminder hooks are registered — `kvb-dream` points each agent at `/kvb-dream` at most once every twelve hours (stamped per session in `~/.claude/.dream-stamps/`), and `kvb-coach` runs its short form at the first prompt of every full hour, once across all agents (stamped in `~/.claude/.coach-hours/`); 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. The `kvb-org-radio` skill registers three hooks: its prompt hook delivers `broadcast` and `direct` items on the next prompt, a PostToolBatch hook delivers `security`, `pan-pan` and `mayday` items mid-turn, and an `asyncRewake` Stop hook wakes an idle session for a `mayday` or a `direct` item sent with `--wake`. The PreToolUse hook of the `kvb-org-queue` skill sends heavy commands through `queue.py hold` once the config sets `queue_enforce`. 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.
