Extends Claude's trim_messages pattern to Google so gemma-4-31b-it (262144 token cap) stops throwing 400 INVALID_ARGUMENT on bursty test_failure payloads (AGENT-3JR/3JS/3JT/3JV, 2026-04-20 gitautoai/website PR 810, conversation jumped 11855 -> 262144+ tokens in 9s at new chat_with_agent invocation). trim_messages_to_token_limit now takes a count_tokens_fn callback; Claude and Google each supply their own count_tokens_* function via functools.partial. Shared trim + message_to_dict moved to services/messages/ so they aren't Claude-specific. Added CONTEXT_WINDOW and MAX_OUTPUT_TOKENS to constants/google_ai.py matching constants/claude.py. Also enables pytest --import-mode=importlib both in our own pytest.ini and in run_pytest_test.py so duplicate test filenames (e.g. test_count_tokens.py in both claude/ and google_ai/) coexist without the 'import file mismatch' collection error.
