Move docs/ package mirror into document-navigator plugin

Relocate the ~6k-file docs tree from the repo root into
plugins/document-navigator/docs/ so the plugin is self-contained and
portable. docs/superpowers/ (specs and plans) stays at the repo root.

Moved via cp+rm rather than git mv because directory rename() fails with
EPERM on this WSL /mnt DrvFs mount; git rename-detection pairs the
identical-content files at commit time.

+# @suaveplan/audio-ir-room-plugin-club - Original audio-ir content package: ships the bundled `club1.wav` and `club2.wav` room impulse responses, registered through @suaveplan/storage-uri-plugin-bundle and @suaveplan/audio-ir-core. Universal; bundle-only content package.
+
+Original audio-ir content package. Ships two bundled room impulse responses (`club1.wav`, `club2.wav`) wired through the `@suaveplan/audio-ir-*` family.
+
+This package is the canonical example of the **bundle-only** content-package pattern in the IR family — every future `audio-ir-{family}-plugin-<name>` package that ships only local files follows this shape.

+## Install
+
+```bash
+bun add @suaveplan/audio-ir-room-plugin-club
+```
+
+Peer-installed alongside `@suaveplan/audio-ir-core`, `@suaveplan/storage-uri`, `@suaveplan/storage-uri-plugin-bundle`.
+
+## Quick start
+
+```ts
+import {
+    createIrRegistry,
+    createUriPluginCollector,
+} from "@suaveplan/audio-ir-core";
+import { register } from "@suaveplan/audio-ir-room-plugin-club";
+import { createIrLoader } from "@suaveplan/audio-ir-loader";
+import { createStorageUriResolver } from "@suaveplan/storage-uri";
+import { nodeFileFetch } from "@suaveplan/storage-uri-plugin-bundle/node-fetch";
+import { decodeWav } from "@suaveplan/audio-decode-wav";
+
+const registry = createIrRegistry();
+const collector = createUriPluginCollector();
+register(registry, collector, { fetch: nodeFileFetch }); // omit `fetch` in the browser
+const resolver = createStorageUriResolver(collector.plugins);
+
+const loader = createIrLoader({
+    registry,
+    resolver,
+    decoders: { wav: decodeWav },
+});
+
+const club1 = await loader.load("club-club1");
+const club2 = await loader.load("club-club2");
+```
+
+## Manifest
+
+| `id` | URI | Channels | Sample rate | Gain |
+|---|---|---|---|---|
+| `club-club1` | `bundle://audio-ir-room-plugin-club/club1.wav` | 2 | 44 100 Hz | 0 dB |
+| `club-club2` | `bundle://audio-ir-room-plugin-club/club2.wav` | 2 | 44 100 Hz | 0 dB |
+
+Channels and sample rate are decoded at manifest-authoring time; the loader re-validates and throws `AUDIO_IR_LOADER.MANIFEST_MISMATCH` on disagreement.
+
+## Modules
+
+- `./manifest` — `manifest: IrManifest`, `BUNDLE_PACKAGE_SLUG`, `MANIFEST_SLUG`.
+- `./register` — `register(registry, collector, options?)` (collector pattern).
+
+The root barrel re-exports every public binding so `import { register } from "@suaveplan/audio-ir-room-plugin-club"` is equivalent to the subpath form.
+
+## Browser vs Node
+
+- **Browser**: omit `options.fetch` in `register` — `globalThis.fetch` reads the bundled URL directly.
+- **Node**: pass `register(registry, collector, { fetch: nodeFileFetch })` from `@suaveplan/storage-uri-plugin-bundle/node-fetch` — Node's undici-backed global `fetch` refuses `file:` URLs.
+
+## License & sources
+
+This package is published under the MIT license. Both IR captures (`club1.wav`, `club2.wav`) originate from the operator's Mountain Duck media library at `/media/_/audio/ir/room/club{1,2}.wav` and are redistributed inside Suaveplan under the same MIT license. The IR samples themselves are room captures with no upstream proprietary attribution requirement.
+
+The `IrManifestEntry.source` field on each entry records the Mountain Duck origin path so a future operator can reproduce the import end-to-end.
