feat(cli): add unified user operations entrypoint

Add scripts/obsidian-wiki-ops.py as the repo-local command surface for common wiki, Kingdee, timer, daily update, and MCP operations.

Route the existing business and MCP shell wrappers through the unified entrypoint for compatibility, and update docs to recommend the single command path.

Validation: python3 -m unittest discover -v; python3 -m compileall obsidian_wiki tests scripts; git diff --check.
