<objective>
## Goal
Rename project from FanucProgramManager to NcProgramManager: namespace, assembly, project files, test folder, and delete dead legacy file.

## Purpose
Product is no longer Fanuc-only. Name FanucProgramManager is wrong. NcProgramManager reflects multi-CN scope.

## Output
- All namespaces: `FanucProgramManager` → `NcProgramManager`
- Project/solution files renamed
- Test folder renamed
- `FANUCMachine.cs` deleted (zero references outside itself)
- Solution builds with no errors
</objective>

<context>
## Project Context
@.paul/PROJECT.md
@.paul/STATE.md

## Key Files
@FanucProgramManager.csproj
@FanucProgramManager.sln
@Properties/AssemblyInfo.cs
@FanucProgramManager.Tests/FanucProgramManager.Tests.csproj
</context>

<acceptance_criteria>

## AC-1: Namespace renamed everywhere
```gherkin
Given any .cs file in the project
When opened
Then namespace declarations and using directives reference NcProgramManager (not FanucProgramManager)
```

## AC-2: Project and solution files updated
```gherkin
Given the renamed solution
When opened in Visual Studio or built with msbuild
Then assembly name is NcProgramManager, test assembly is NcProgramManager.Tests, project reference resolves
```

## AC-3: Dead code removed
```gherkin
Given FANUCMachine.cs
When cleanup completes
Then file does not exist (confirmed zero references before deletion)
```

<tasks>

<task type="auto">
  <name>Task 1: Replace FanucProgramManager string in all .cs files</name>
  <files>All *.cs files under project root (recursively)</files>
  <action>
    Run find+sed to replace all occurrences of `FanucProgramManager` with `NcProgramManager` in every .cs file:

    ```bash
    find /path/to/project -name "*.cs" -exec sed -i 's/FanucProgramManager/NcProgramManager/g' {} +
    ```

    This covers:
    - `namespace FanucProgramManager` → `namespace NcProgramManager`
    - `namespace FanucProgramManager.Cnc` → `namespace NcProgramManager.Cnc`
    - `using FanucProgramManager;` → `using NcProgramManager;`
    - `using FanucProgramManager.Cnc.Fanuc;` → `using NcProgramManager.Cnc.Fanuc;`
    - All sub-namespaces (.Cnc, .Cnc.Fanuc, .Cnc.Heidenhain, .Cnc.Siemens, .Cnc.Mitsubishi, .Cnc.Models)
    - `InternalsVisibleTo("FanucProgramManager.Tests")` in AssemblyInfo.cs
    - `AssemblyTitle`, `AssemblyProduct` in AssemblyInfo.cs

    Avoid: editing binary files, NuGet package cache, obj/bin folders.
    Use: `-not -path "*/obj/*" -not -path "*/bin/*" -not -path "*/.paul/*"`

    FANUCMachine.cs (delete),

  </files>
  <action>
    1. Delete `FANUCMachine.cs` — confirmed dead: no file outside itself references `FANUCMachine`. Also remove its `<Compile Include="FANUCMachine.cs" />` entry from csproj.

    2. Rename project file:
       ```bash
       mv FanucProgramManager.csproj NcProgramManager.csproj
       ```

    3. Rename solution file:
       ```bash
       mv FanucProgramManager.sln NcProgramManager.sln
       ```

    4. Rename test folder (this moves all contents):
       ```bash
       mv FanucProgramManager.Tests NcProgramManager.Tests
       ```

    5. Rename test csproj inside the now-renamed folder:
       ```bash
       mv NcProgramManager.Tests/FanucProgramManager.Tests.csproj NcProgramManager.Tests/NcProgramManager.Tests.csproj
       ```

    Order matters: rename folder BEFORE renaming csproj inside it.
    The .sln file was already updated in Task 2 to reference new paths — verify paths match after rename.

    Avoid: renaming `Cnc/Fanuc/` folder or any Fanuc-prefixed class files — `FanucMachine`, `FanucConnectionConfig` etc. are manufacturer-specific names, keep them.

## DO NOT CHANGE
- `Cnc/Fanuc/` folder name — Fanuc is a manufacturer name, not a project name
- `FanucMachine.cs`, `FanucConnectionConfig.cs`, `FanucCapabilities.cs` — manufacturer-specific class names, keep
- `FanucProgram.cs` — Fanuc ISO program format class, name is accurate
- `FanucProgramParsingTests.cs` — test file for FanucProgram, name is accurate
- `IFanucMachine.cs` — interface name correct (Fanuc-specific capability set)
- Any class name that describes Fanuc-specific behavior

## SCOPE LIMITS
- No Italian → English rename in this plan (deferred)
- No logic changes — pure rename/delete only
- No NuGet package changes
- No new files created

</boundaries>
