project-entry

当进入一个新的项目目录时触发新鲜度扫描。在工作目录发生变化、用户提到“正在处理X项目”、“切换到X”、“打开X”，或者新的项目路径首次出现在对话中时使用。

When entering a project directory, check if docs-manager has a registered library for this location:

Run bash ${CLAUDE_PLUGIN_ROOT}/scripts/index-query.sh --search "$(basename $(pwd))" to check for matching libraries
If no match: skip silently — this project isn't managed
If match found: run bash ${CLAUDE_PLUGIN_ROOT}/scripts/index-query.sh --library "<name>" to get all docs
Check each doc's last-verified date — flag any >90 days old
Check queue for any pending items related to this library
If concerning items found, inject brief context: "N documentation items queued for this project."

Do not interrupt the user's workflow. Only surface findings if there are actionable items.
