 		Fix concurrent proxy client operations with session isolation (#1083) 
* 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.

🤖 Generated with [Claude Code](https://claude.ai/code)

Co-Authored-By: Claude <noreply@anthropic.com>

* Update proxy documentation for new client factory pattern

Documents the new session management behavior, client_factory parameter,
and concurrent operation safety introduced in v2.10.3 to fix #1068.

* Remove deprecation of client parameter and update documentation

- Undeprecated FastMCPProxy client parameter
- Made client_factory the advanced option for custom control
- Added detailed explanation of how client factories work internally
- Removed outdated note about proxy feature limitations
- Removed fabricated Advanced Usage section

* Re-do proxy documentation

* Fix deprecated client parameter to provide session isolation

0600834da4 Fix single-element list unwrapping in tool content 
Single-element lists like [1] were being incorrectly unwrapped to "1"
in unstructured content while multi-element lists remained as lists.
This created inconsistent behavior where the structure was lost for
single items.

This fix ensures lists always preserve their structure in unstructured
content regardless of length, making behavior consistent and predictable.

Also removes pretty-printing from JSON serialization for more compact
output across tools, prompts, and resources.

Fixes #1064

a7f14d90a4 Implement client-side argument serialization with focused tests 
- Add pydantic_core.to_json() serialization for non-string prompt arguments
- Update type annotations to accept dict[str, Any] instead of dict[str, str]
- Add focused tests covering specific scenarios:
  * Client always serializes non-string args regardless of server types
  * Integration with server-side type conversion
  * Client serialization error with specific PydanticSerializationError
  * Server deserialization error with specific McpError match

This ensures MCP protocol compliance while maintaining developer experience
with typed arguments.
