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.
Replace per-command shell wrappers with a single scripts/mcp_service.sh entrypoint that forwards subcommands to manage_mcp_service.py.
Update docs and tests so remote MCP service management stays on the consolidated command surface.
