MagAgent 0.32.4

MagAgent 0.32.4 tightens the interactive artifact-writing loop after the latest smoke tests. It fixes file mutation verification so a later successful absolute-path write clears an earlier relative-path failed write for the same file, suppresses noisy LiteLLM remote model cost-map network warnings in sessions, and strengthens recovery guidance after missing write_file content so the model retries the artifact write instead of drifting back into research/read loops.\n\nValidation: ruff check src tests, pytest -q, magent docs doctor, python -m build, and twine check all passed.
