Apply Sbroenne prefix to all project namespaces, simplify CLI executable name, and implement .NET best practices

[Copilot]

Problem

The project had inconsistent naming conventions across solution files, namespaces, and documentation. Additionally, the project needed a comprehensive review to ensure compliance with .NET best practices for production-ready NuGet packages. Specifically:

• The CLI project used ExcelMcp.* namespaces while Core and McpServer used Sbroenne.ExcelMcp.*
• Solution file was named ExcelMcp.sln without the company prefix
• Projects lacked explicit AssemblyName and RootNamespace properties
• References to the old repository sbroenne/ExcelCLI existed throughout documentation
• Product branding mixed ExcelCLI and ExcelMcp.CLI inconsistently
• .NET version references were outdated (8.0 instead of 10.0)
• Legacy test folder not in solution was still tracked
• CLI executable name was too verbose for command-line usage
• Missing XML documentation generation for library projects
• Missing deterministic build settings for reproducible binaries
• No package validation enabled for NuGet packages
• Documentation had inconsistent references to the CLI executable name
• Copilot instructions focused on CLI commands instead of MCP server workflows
• Intermediary documentation files cluttered the repository

Changes

1. Naming Standardization

Solution & Projects:

• Renamed ExcelMcp.sln → Sbroenne.ExcelMcp.sln
• Added explicit AssemblyName and RootNamespace to all 5 projects
• CLI AssemblyName: Simplified to excelcli for user-friendly executable name
• CLI RootNamespace: Maintained as Sbroenne.ExcelMcp.CLI for code organization

Namespaces (16 files):

// Before
namespace ExcelMcp;
namespace ExcelMcp.Commands;

// After
namespace Sbroenne.ExcelMcp.CLI;
namespace Sbroenne.ExcelMcp.CLI.Commands;

Using Statements (7 files):

// Before
using static ExcelMcp.ExcelHelper;

// After
using static Sbroenne.ExcelMcp.CLI.ExcelHelper;

2. Repository & Product References

Directory.Build.props:

<!-- Before -->
<Product>ExcelCLI</Product>
<PackageProjectUrl>https://github.com/sbroenne/ExcelCLI</PackageProjectUrl>

<!-- After -->
<Product>Sbroenne.ExcelMcp</Product>
<PackageProjectUrl>https://github.com/sbroenne/mcp-server-excel</PackageProjectUrl>

Program.cs: Updated 14 branding references from ExcelCLI to ExcelMcp.CLI and fixed repository URLs

Original prompt

Please chech if my project and solution files are according to best practices. I think I am missing the Sbroenne. prefix

[Chronological Review: The conversation began with the user requesting to rename the project to "ExcelMcp.CLI" and update all documentation accordingly. The user then specified that the README should focus on the MCP server, with CLI details in a separate file. The user expressed a desire for different build and release processes for the MCP server and CLI, as well as splitting installation instructions. The user later requested to adopt a specific approach for the MCP server based on a Microsoft documentation link, including changing to .NET 10 SDK as a prerequisite. The user also wanted to split build workflows and test cases between MCP and CLI. The conversation continued with the user asking for direct updates to the files and to avoid using certain commands. The user raised a question about naming conventions for the solution and namespace, suggesting they should be prefixed with "Sbroenne." The user noted that some project documentation was outdated and requested a review to ensure it aligns with best practices, particularly regarding installation instructions and links to old GitHub projects.]

[Intent Mapping:

1. "Rename this project to ExcelMcp.CLI since it is a cli and update all the docs."
2. "Make sure that this readme focuses on the Mcp server. You should mention the CLI but that should be in its own file."
3. "I want our MCP Server to use this approach... We need to change to .NET 10 SDK as a prereq."
4. "Please also split-up the build workflows as well and delete old workflow files."
5. "Can you please update the files directly."
6. "Also don't use Get-ChildItem - modify it directly."
7. "Shouldn't my Solution and namespace not be prefixed with my company name 'Sbroenne'?"
8. "Please review the project - I still see links to the old GitHub projects for examples."
9. "The install instructions for the mcp servers do not match..."]

[Technical Inventory:

• Technologies: .NET 10 SDK, NuGet
• Documentation: RELEASE-STRATEGY.md, CLI.md, COMMANDS.md
• Tools: GitHub for version control, winget for installation

[Progress Assessment:

• Completed: User has provided detailed requests for documentation updates and project structure.
• Pending: Implementation of the requested changes, including renaming, restructuring documentation, and ensuring compliance with naming conventions.]

[Context Validation: All critical information for continuation is captured, including user requests for documentation updates, project renaming, and adherence to best practices.]

[Recent Commands Analysis:

• Last Agent Commands: User requested direct updates to files and to avoid using Get-ChildItem.
• Tool Results Summary: No specific tool results were returned as the user requested direct modifications.
• Pre-Summary State: The agent was actively working on updating the RELEASE-STRATEGY.md file and ensuring it aligns with user requests when the token budget was exceeded.
• Operation Context: These commands were executed to fulfill the user's goals of renaming the project, restructuring documentation, and ensuring best practices are followed.]
