NEW: uvx support for all entry points

no installation needed: prepend uvx to all commands

Excel:

uvx excel-vba edit -f myfile.xlsm --vba-directory .\src\VBA

Word:

uvx word-vba edit -f myfile.docm --vba-directory .\src\VBA

Access:

uvx access-vba edit -f myfile.accdb --vba-directory .\src\VBA

PowerPoint:

uvx powerpoint-vba edit -f myfile.pptm --vba-directory .\src\VBA

Note: The uvx command invokes a tool without installing it — same as: uv tool run excel-vba
