Vendor Cordis framework packages as source

cordis 4.0.0-rc.6, plugin-loader, -include, -group, -timer, -hmr,
-logger-console, cosmokit 1.8.1, schemastery 3.18.0 — copied from the
cordis-workspace checkout, flattened under vendor/, original npm names,
private: true. vendor/README.md is the manifest: upstream repos +
commit SHAs, local-modification log, sync procedure.

Local modification: hmr's locale YAML imports and .i18n() call removed
(avoids a runtime YAML import hook we don't vendor).

+# @cordisjs/plugin-logger-console
+
+Console exporter for the built-in Cordis logger service.
+
+## Usage
+
+```ts
+import { Context } from 'cordis'
+import ConsoleLogger from '@cordisjs/plugin-logger-console'
+
+const root = new Context()
+await root.plugin(ConsoleLogger, {
+  showDiff: true,
+  levels: {
+    default: 2,
+    hmr: 3,
+  },
+})
+
+root.logger('app').info('started')
+```
+
+## Config
+
+| Field | Description |
+| --- | --- |
+| `colors` | Color support level, or `false` to disable colors. |
+| `maxLength` | Maximum rendered line length before truncation. |
+| `levels` | Per-logger minimum level map. |
+| `showDiff` | Show elapsed time since the previous message. |
+| `showTime` | Timestamp template. |

+passes log arguments through to `console`.
