* Always emit a tool title, derived from name when unset
Some MCP clients (e.g. ChatGPT) drop tools with no `title` instead of
falling back to `name` for display as the spec allows. Deriving a
default title in Tool.to_mcp_tool() fixes this for every tool built on
top of it, including the search-transform, code-mode, and session
proxy tools that never set one explicitly.
Fixes#4414
* Derive fallback title from the overridden name, document it
Addresses Codex review on #4694.
* Resolve title precedence from effective overrides
* Normalize mapping annotations before deriving the title
Engine modules (keys, context snapshot, docket lifespan, worker CLI,
client handles) move intact; SEP-1686 wire modules park in _legacy_wire
for adaptation to SEP-2663. Core keeps task=True declaration on tools
only and raises at serve time until the tasks extension is registered.

* fix: suppress output schema for ToolResult subclass annotations
* use issubclass_safe/is_class_member_of_type for ToolResult subclass checks
* use parsed_fn.return_type for ToolResult check in transform fallback
* pin pydantic-monty to 0.0.8
* rename tool/prompt/resource base modules to avoid decorator name shadow
* add sys.modules shims for old submodule import paths
* preserve original module paths in deprecation warnings
* clarify when sys.modules shims can be removed
* Propagate x-fastmcp-wrap-result flag in tool result _meta
