feat(kvb-org-radio): split radio and post, add kvb-org-update

The radio (call, broadcast, security, pan-pan, mayday) reaches its addressee at the next tool step and wakes it. The post (post with --to, newsletter without, call receipts) arrives through a new Stop hook when the turn ends and never wakes. Legacy rows map onto the two channels and send direct stays as an alias. A PreToolUse hook holds the mayday's radio silence for writing tools and Bash. Only the sender, helpers who join with radio.py assist, bare radio.py calls and the config's allowed commands pass, and any shell operator or parse error blocks. kvb-org-update announces changed skills as one newsletter. Callers moved to send call --to.

🎯 Fix: 90 %

-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 `~/.claude/agents-council/config.json` exists, and because its hooks run that config's commands outside the sandbox, the install adds `Edit(~/.claude/agents-council/**)` to `permissions.deny`, which also covers Write in every permission mode. 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`, and holds a held command to the settings' Bash deny and ask rules, which see only `queue.py hold`. The global install also installs the MEDUSA security scanner with pipx for `kvb-check-security`, unless `medusa` is already on the PATH. 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`. Every hook runs `/usr/bin/python3 -I`, so neither the `python3` of a sandbox-writable virtualenv on the `PATH` nor `PYTHONPATH` reaches the hooks, which run outside the sandbox; older bare `python3` hook entries are rewritten. The reminder hooks run `/usr/bin/bash` and pin `PATH=/usr/bin:/bin`, and the council scripts keep only the `PATH` directories this uid cannot write (`skills/kvb-org-organize/scripts/hookpath.py`), so no binary an agent plants on the inherited `PATH` runs outside the sandbox. Existing settings are preserved.

The `kvb-org-radio` skill registers five hooks: its prompt hook and a PostToolBatch hook deliver the immediate radio (`call`, `broadcast`, `security`, `pan-pan`, `mayday`) mid-turn, a Stop hook delivers the post (`post`, `newsletter` and call receipts) when the turn ends, an `asyncRewake` Stop hook wakes an idle session for the radio, and a PreToolUse hook refuses every writing action while a mayday holds, except those of its sender and of the agents that join it with `radio.py assist`. The PreToolUse hook of the `kvb-org-queue` skill sends heavy commands through `queue.py hold` once the config sets `queue_enforce`, and holds a held command to the settings' Bash deny and ask rules, which see only `queue.py hold`.
