Pull #80

github

v0.4.1 is implemented. All stages complete; nothing committed or published.

Public `Blob.properties/4` and `Blob.exists?/4` (HEAD), shared `head_blob/5`, `download_stream/4` on `properties/4`, tests/docs/version bump.

```elixir
@spec properties(Client.t(), String.t(), String.t(), keyword()) ::
  {:ok, properties()} | {:error, Error.t()}

@spec exists?(Client.t(), String.t(), String.t(), keyword()) ::
  boolean() | {:error, Error.t()}
```

`properties` → `%{content_length, content_type, etag, last_modified, metadata}`.
`exists?` → `true` / `false` / `{:error, _}` (only not-found → `false`).

| Stage | Status |
|-------|--------|
| 0 Audit | Done — baseline green |
| 1 properties | Done |
| 2 exists? | Done (`head_blob`, not nested `properties`, so malformed length ≠ false-negative) |
| 3 download_stream | Done |
| 4 Azurite | Done — 19 azurite tests |
| 5 Docs | Done |
| 6 0.4.1 | Done |

`mix verify` passed (93.1% cover). `mix test --only azurite` — 19/0.
