feat: stage 0, an empty RunicNPC that releases through CI

The repository RunicNPC is built in (docs/runicnpc/PLAN.md §9, stage 0):

- plugin/RunicNPC.cs: `// Requires: Kits` (D217), `[Info]` with the 0.0.0
  placeholder the release stamps, `RunicNpc_ApiVersion()` (API 1), and
  `rnpc.status`, which reports the version and which hooks have fired. It
  spawns nothing.
- plugin.toml: the API version, the framework floors it was loaded on
  (Oxide 2.0.7726, Carbon 2.0.259) and requires_plugins = ["Kits"].
- scripts/checkPlugin.js, adapted from Rust-Plugins': every hook listed and
  void unless written down; chat-command signatures; every RunicNpc_ call
  reachable by Call (the HumanNPC trap, PLAN.md §1.2); ApiVersion,
  `// Requires:` and [Info] agreeing with plugin.toml. 23 self-tests, including
  the real plugin and a CRLF checkout.
- PR Checks on PRs into main and edge; the release workflow on main, with
  Rust-Plugins' release engine unchanged and an adapter that ships
  runicnpc-<ver>.tar.gz (runicnpc/RunicNPC.cs + manifest.json) and SHA256SUMS.
  No bundle dispatch until stage 4.
- tools/: the rig panel scripts, with the panel and server ids moved into a
  git-ignored tools/rigs.json. `con.js` became `console.js`: CON is a reserved
  device name on Windows, and git there cannot open the file.
- README, CONTRIBUTING (edge-based flow, AI disclosure, borrow-not-copy),
  SECURITY, the code of conduct, issue and PR templates.

`feat:` so the cutover to main cuts the first release, 0.1.0.
