LXC deployment: live config for agentd-01, oregon rollback config, win10 helpers and board protocol in the repo

- config/agentd.yaml is now the agentd-01 live config (state /var/lib/plane-agentd, logs /var/log/plane-agentd);
  config/agentd.oregon.yaml keeps the oregon dispatcher settings for rollback (cron/agentd-tick.sh uses it).
- cron/agentd-tick-lxc.sh: the LXC cron entry.
- tools/win10/: win10-ps.sh / win10-put.sh (vault client dir via AGENT_ACCESS_HOME); relative helpers_dir
  resolves against the repo, default tools/win10.
- config/protocols/gwent-board-protocol.md: copy of gwent/design/board-protocol.md used in prompts.
- agentd.log_dir (default state_dir).
- smoke --watch: create the item and wait for the scheduled dispatcher instead of ticking locally.
