feat(sdk): ESM multi-fichiers + storage plugin-owned (#134/#139)

Documente et illustre deux contrats SDK :

- Multi-fichiers ESM : le `main` du manifeste peut importer d'autres
  fichiers du package via specifiers relatifs, servis par IdeA sur
  `idea-plugin://` (build `tsc` non bundlé). Le packager embarque tout
  `dist/**/*.js` et vérifie la présence du `main`. Les bare specifiers
  (`node_modules`) restent hors contrat : à bundler ou vendorer.
- Storage plugin-owned : `ctx.storage` est la place canonique de l'état
  interne du plugin (compteurs, flags, préférences, caches), hors des
  fichiers projet. Les APIs workspace/config restent pour le contenu
  project-owned.

L'exemple hello-plugin est éclaté en modules (constants, core/layout,
core/workspace, core/storage) pour exercer l'import relatif et le storage.

@ -8,22 +8,37 @@ It exercises the current plugin primitives end to end:
- menu entry: `hello-plugin`;
- command: `hello-plugin`, returning `hello-world`;
- layout contribution: `hello-plugin.hello-world`, rendered as `hello-world`.
- plugin-owned storage: activation count, command run count and initialization flag;
- tooling capability: logs the focused workspace project when `ctx.services` is available.
The source is intentionally split across multiple TypeScript modules:
- `src/index.ts` is the manifest entrypoint and imports relative ESM modules;
- `src/constants.ts` owns shared command/layout identifiers;
- `src/core/layout.ts` and `src/core/workspace.ts` hold feature logic.
- `src/core/storage.ts` keeps plugin-owned counters and flags in `ctx.storage`.
The build uses plain `tsc`; it does not bundle the plugin into one file. The archive includes all
compiled `dist/**/*.js` files so IdeA can load `dist/index.js` and serve its package-relative imports
through `idea-plugin://`. Runtime imports from `node_modules` are outside this contract: vendor them
as relative files or bundle them into the plugin output before packaging.
```sh
npm run typecheck:examples
npm run package:hello-plugin
```
The installable archive is emitted at `examples/hello-plugin/build/hello-plugin-0.1.0.zip`.
It contains `idea-plugin.json` at the ZIP root and the compiled ESM entrypoint at
`dist/index.js`, matching the manifest `main` field.
It contains `idea-plugin.json` at the ZIP root and the compiled multi-file ESM output under `dist/`,

## Diagnostics
During activation the plugin logs:
- whether the command and layout runtime registries are available;
- whether plugin-owned storage is available;
- activation count and initialization state stored through `ctx.storage`;
- successful registration of the `hello-plugin` command;
- successful registration of the `hello-plugin.hello-world` layout;
- availability of the workspace service from the `tooling` runtime capability;
