Restructure sample: rename projects, flatten client dir, @typeshim→@client, merge people-ui into app (#94)

Cleans up the sample project layout — flatter structure, consistent
naming, fewer npm packages.

## Changes

- **Project renames**
  - `TypeShim.Sample` → `Client.Library` (dir, csproj, C# namespaces)
  - `TypeShim.Sample.Server` → `Server` (dir, csproj, C# namespaces)
  - `Sample.slnx` updated; `Server.csproj` project reference updated

- **Flatten client directory**
- `TypeShim.Sample.Client/` removed; contents (`package.json`,
workspaces, `.gitignore`, etc.) lifted into `sample/` root
  - `.esproj` / `.esproj.user` deleted; removed from `Sample.slnx`
  - `Client.Library.csproj` `<OutputPath>` updated to new path

- **`@typeshim` → `@client`**
- Directory, all `package.json` names, TypeScript imports, string
literals, `.gitignore` glob pattern

- **Merge `@client/people-ui` into `@client/app`**
  - Components moved to `@client/app/src/people/`
  - `@client/app` no longer depends on `@client/people-ui`
- `build:people` script removed; `package-lock.json` and root
`tsconfig.json` references cleaned up
  - `@client/people-ui` package deleted
