v0.5.1

v0.5.1 Release Notes

This patch release tightens MCP patch operation constraints and updates
documentation for backend behavior clarity.

Highlights

• Added a service-level guard for backend-only op mixing:
  • create_chart and apply_table_style can no longer be combined in a
    single request.
• Updated MCP docs and README pages for create_chart constraints:
  • COM-only behavior
  • supported chart types: line, column, bar, area, pie,
    doughnut, scatter, radar
  • chart type aliases: column_clustered -> column, bar_clustered ->
    bar, xy_scatter -> scatter, donut -> doughnut
  • related flag limitations
  • incompatibility with apply_table_style in one request

Notes

• This is a compatibility and correctness-focused patch release with no new
  public tool surface added.
