9fd60025f8 fix: preserve annotation metadata when cloning wrapped partials 
Addresses Codex P1: when reconstructing a partial to strip __wrapped__,
copy over functools.WRAPPER_ASSIGNMENTS (__module__, __qualname__, etc.)
so deferred annotation resolution works correctly.

e3f02374c7 Support functools.partial and centralize callable utilities 
functools.partial objects failed at registration (@mcp.tool didn't
recognize them) and at call time (update_wrapper set __wrapped__
causing Pydantic to ignore bound arguments).

Introduces centralized utilities replacing scattered patterns across
11 files:

callable_utils.py:
- is_callable_object(): TypeGuard replacing inspect.isroutine() in
  7 decorator entry points — recognizes partials as callables
- get_callable_name(): Extracts useful names from any callable type,
  including partials without update_wrapper
- prepare_callable(): Strips __wrapped__, unwraps callable classes
  and staticmethod — replaces 4 duplicated blocks

decorators.py:
- set_fastmcp_meta(): Attaches __fastmcp__ metadata through __func__
  for bound methods — replaces 5 identical 2-line blocks

TaskConfig:
- normalize(): Converts bool|TaskConfig|None to TaskConfig — replaces
  4 identical 6-line if/elif/else blocks

No behavior changes beyond the bug fix: existing lambda rejection,
validation, and error handling remain per-module policy.

Closes #3266
