This commit optimizes the HTTPPropagator.extract method, which is a critical hot path that runs on every request. The changes focus on reducing object allocations and avoiding unnecessary work in common scenarios.

  • Avoids allocation on sucessful path: We no longer create an empty Context object unconditionally. If one is found later, we avoid 1 allocation.
  • Adds single-context fast path: In multi-style extraction mode, if only one context is found (a common case), we now use it directly instead of calling the more expensive _resolve_contexts method.
  • Optimizes baggage tagging: The loop for applying baggage as tags is optimized by hoisting attribute lookups (.meta) and method calls (.get_all_baggage_items) out of the loop, reducing overhead per-key.
  • Cleaner baggage logic: Baggage extraction is now explicitly handled once at the end, simplifying the logic within the "extract-first" and "multi-extract" paths.

This commit optimizes the `HTTPPropagator.extract` method, which is a
critical hot path that runs on every request. The changes focus on
reducing object allocations and avoiding unnecessary work in common
scenarios.

* Avoids allocation on sucessful path: We no longer create an empty
  `Context` object unconditionally. If one is found later, we avoid 1
  allocation.
* Adds single-context fast path: In multi-style extraction mode, if
  only one context is found (a common case), we now use it directly
  instead of calling the more expensive `_resolve_contexts` method.
* Optimizes baggage tagging: The loop for applying baggage as tags
  is optimized by hoisting attribute lookups (`.meta`) and method calls
  (`.get_all_baggage_items`) out of the loop, reducing overhead
  per-key.
* Cleaner baggage logic: Baggage extraction is now explicitly
  handled once at the end, simplifying the logic within the
  "extract-first" and "multi-extract" paths.
