* refactor: improve typing with memory stream type aliases
Move memory stream type definitions to models.py and use them throughout
the codebase for better type safety and maintainability.

* refactor: update websocket client to use MessageFrame
Modified the websocket client to work with the new MessageFrame type,
preserving raw message text and properly extracting the root JSON-RPC
message when sending.

* feat: allow lowlevel servers to return a list of resources
The resource/read message in MCP allows of multiple resources
to be returned. However, in the SDK we do not allow this. This
change is such that we allow returning multiple resource in
the lowlevel API if needed. However in FastMCP we stick to
one, since a FastMCP resource defines the mime_type in the decorator
and hence a resource cannot dynamically return different mime_typed resources.
It also is just the better default to only return one resource.
However in the lowlevel API we will allow this.
Strictly speaking this is not a BC break since the new return value
is additive, but if people subclassed server, it will break them.
* feat: lower the type requriements for call_tool to Iterable
Add comprehensive documentation for lifespan support:
- Add usage examples for both Server and FastMPC classes
- Document startup/shutdown patterns
- Show context access in tools and handlers
- Clean up spacing in test files
Adds comprehensive tests for lifespan functionality:
- Tests for both low-level Server and FastMCP classes
- Coverage for startup, shutdown, and context access
- Verifies context passing to request handlers
Introduce ReadResourceContents type to properly handle MIME types in resource responses. Breaking change in FastMCP read_resource() return type.
Github-Issue:#152
The server was ignoring mime types set on resources, defaulting to text/plain
for strings and application/octet-stream for bytes. Now properly preserves
the specified mime type in both FastMCP and low-level server implementations.
Note that this is breaks backwards compatibility as it changes the return
values of read_resource() on FastMCP. It is BC compatible on lowlevel since
it only extends the callback.
