[Bug] v2.0.10 依赖冲突: numpy/scipy/chonkie 版本不兼容

[WuSho1995]

环境信息

• MemOS 版本: v2.0.10 (从 v2.0.8 升级)
• 系统: Linux (飞牛 NAS, x86_64)
• Python: 3.11.2

依赖冲突详情

chonkie 1.6.1 要求 numpy>=2.0.0，但 scipy 1.10.1 要求 numpy<1.27.0

两者打架：

• 安装 chonkie → numpy 升到 2.4.3 → scipy 崩 (ImportError: numpy.core.multiarray failed to import)
• 降级 numpy 到 1.26.4 → chonkie 又不能用

复现步骤

1. pip install -e . 升级到 v2.0.10
2. 按错误提示安装缺失依赖：pip install chonkie neo4j qdrant-client
3. 启动服务时 numpy/scipy 版本冲突

建议

• pyproject.toml 里把 scipy 升到 1.13+（支持 numpy 2.x），或明确指定兼容版本范围

Summary: ## Summary

Fixes #1342: numpy / scipy / chonkie version conflict.

Root cause. pyproject.toml [tool.poetry.group.eval] declared scipy = "^1.10.1". scipy 1.10.x pins numpy<1.27.0 (verified via the PyPI JSON metadata), while chonkie>=1.6.0 requires numpy>=2.0.0. The two constraints are jointly unsatisfiable, so any environment that ends up with both packages (the user's reproduction installs chonkie on top of an apt-installed scipy 1.10.x) raises ImportError: numpy.core.multiarray failed to import.

Fix. Bumped the eval-group scipy floor from ^1.10.1 to ^1.13.0 (scipy 1.13 is the first release supporting numpy 2.x) and added two explanatory comments — one near the bumped floor and one above the chonkie entry in the mem-reader extras — so future readers see the numpy 2.x implication.

Scope. scipy is only imported by evaluation/scripts/longmemeval/lme_eval.py and evaluation/scripts/locomo/locomo_eval.py; nothing under src/memos/ references it (grep clean). The change is therefore constraint-only, no source code path is affected.

Verification. ruff check pyproject.toml → "All checks passed!"; ruff format --check pyproject.toml → no diff; pytest tests/chunkers/ → 3 passed in 4.26s; TOML reparsed via tomli.load reports eval scipy= ^1.13.0. The committed poetry.lock already resolves scipy to 1.15.3 / 1.16.0 and numpy to 2.2.6 / 2.3.1, all of which satisfy the new ^1.13.0 floor, so a re-lock would be a no-op and is deferred to the pre-commit poetry-lock hook on the maintainer's machine.
