docs: correct stale tool count and library version in the plugin shell

The doc-sync sweep at close time caught three facts this change had just
invalidated, all in plugins/che-word-mcp/CLAUDE.md:

- "242 tools（binary v3.20.0 tools/list 實測）" — the count is 245, measured
  the same way the original claim was: by running the released v4.0.0 binary as
  an MCP server and reading tools/list. v3.20.0 is several releases stale.
- "Built on ooxml-swift v0.24.0" and the same figure in the Binary Dependency
  table — it is v3.0.1.

The che-word-mcp README's own version-history rows were checked and left alone:
they describe what each past release did and are correctly frozen. A v4.0.0 row
was added there separately.

Also bumps the submodule pointer.

 ## Purpose
 
-Microsoft Word (.docx) MCP plugin. Wraps the [CheWordMCP](https://github.com/PsychQuant/che-word-mcp) Swift binary via auto-download wrapper. **Swift-native OOXML manipulation** — reads and writes .docx without requiring Microsoft Word installation. 242 tools（binary v3.20.0 `tools/list` 實測）cover the full Office.js OOXML Roadmap P0 set ([#43](https://github.com/PsychQuant/che-word-mcp/issues/43) closed 100%).
