* Refactor FastMCPProxy into ProxyProvider
Move proxy functionality from custom manager classes to the Provider pattern:
- Create ProxyProvider that implements the Provider interface
- Move all proxy code to src/fastmcp/server/providers/proxy.py
- Keep FastMCPProxy as a convenience wrapper using ProxyProvider
- Add deprecation warning when importing from old location
- Convert handler classmethods to module-level functions
- Remove redundant get_* methods (base class defaults work)
* Remove unused Components class, simplify TaskComponents()
* Replace type: ignore[attr-defined] with isinstance assertions in tests
* Fix isinstance assertions in failing tests
- Fix enum test to check for ResponseEnum instead of str
- Fix binary resource test to check for BlobResourceContents instead of TextResourceContents
- Fix Root type tests to check attributes directly instead of isinstance checks
* Fix type errors without using type: ignore
- Remove execution methods from TransformingProvider (only handles transformations)
- Add execution methods to base Provider class with default implementations
- Fix type narrowing in tests using cast() instead of type: ignore
- Fix PromptResult type handling in prompt render tests
- Fix type narrowing in middleware test for arguments and structured_content
Proxied tool results now properly forward the meta attribute from upstream servers through ProxyToolManager and ProxyTool.

Prevents enable/disable operations on mirrored components (tools, resources, prompts retrieved from proxy servers). Users must create local copies with .copy() and add them to their server to modify them. Local components take precedence over mirrored ones.

* Refactor Client session state with ClientSessionState dataclass
Fixes#1068 by introducing ClientSessionState to encapsulate session management
attributes, simplifying Client.new() and preventing concurrent proxy client
context mixing through client factory pattern.
