#301 added the `title` field to the `Resource`/`ResourceTemplate` schema
classes and the `McpResource`/`McpResourceTemplate` attributes, but the
manual registration methods on `Builder` were never updated — so manual
registration could not set a resource title, unlike tools and prompts.
Add a `$title` parameter between `$name` and `$description` (matching
`addTool()`/`addPrompt()`) and propagate it through `ArrayLoader` when
constructing the `Resource`/`ResourceTemplate` objects.
