fix(review): adopt every documented backend protocol, not just get_response

Review found the Agent(llm=<object>) fix was incomplete, and it was right.
Verified by running it:

    chat_completion-only backend -> self.llm=<object>  custom=False   BUG
    get_response backend         -> self.llm="custom/..." custom=True  ok

llm/protocols.py documents two more backend surfaces besides get_response:
LLMProviderProtocol via chat/achat, and UnifiedLLMProtocol via
chat_completion/achat_completion. A backend implementing either still fell
through to the plain OpenAI branch, where the object became the model
identifier and the turn went to the wrong backend -- the same defect the
branch was added to fix, for a different protocol.

Detection now duck-types across all of them. Five tests, including two
controls: a plain object with no backend method is still NOT adopted, and a
string llm is unaffected.

-# Why this exists
-#
-# praisonai-agents has ~11,900 tests. Until this gate, CI executed 15 of them:
-# one smoke step in test-optimized.yml naming two files. Everything else was
-# collected by nobody.
-#
-# The cost of that showed up as two test modules that could not even be
-# IMPORTED -- they referenced symbols moved or replaced months earlier, so 19
-# tests silently contributed nothing while still appearing to exist. A failing
-# test is loud; a test that never collects is not.
-#
-# This job started as collection-only, because running the suite would have gone
-# red on arrival: 297 pre-existing failures nothing had been enforcing, and a job
-# that is red the day it lands teaches people to ignore it. Then a curated
-# green-set, ratcheted upward.
-#
-# Both are gone. The unit suite now runs in full and passes: 9373 tests, 0
-# failures. The `collect` job stays because it is the cheaper, stricter signal --
-# it cannot pass while a test file is unimportable, and it says so in 40s.

+    None of its methods are invoked by production code: the live execution paths
+    use ``_chat_impl`` / ``_execute_unified_chat_completion`` (in ``chat_mixin.py``)

+    window; it will be removed from the ``Agent`` MRO after the cycle completes.
     Use ``Agent.chat()`` / ``Agent.achat()`` / ``Agent.execute_tool()`` instead.

-    ``_run_async_in_sync_context`` **is** live production code (the sync
-    tool-calling path in ``tool_execution.py`` depends on it). It has been
-    relocated to the stable ``async_safety.run_async_in_sync_context`` so that
-    removing this deprecated mixin from the MRO is a true no-op. The method here
-    is now only a thin shim kept for the deprecated public methods above.

 implementation with a thin sync bridge, eliminating code duplication between

-
-    A consolidation pass runs off the hot path (typically on a schedule) and
-    merges near-duplicate memories, promotes durable high-value facts into a
-    curated tier, and prunes stale/low-value entries. This result reports what
-    the pass did so callers can log, observe, and enforce loss bounds.

-    existing memory).
-
-    Loss is measured against *original* entries, not the net entry count. When
