🚀 Add Export-Json function for exporting JSON data to files

[Copilot]

This PR implements the Export-Json function to complete the JSON module's core functionality, providing a comprehensive solution for JSON file operations alongside the existing Format-Json and Import-Json functions.

Key Features

The Export-Json function provides flexible JSON export capabilities with the following features:

• Dual Input Support: Accepts both PowerShell objects (-InputObject) and JSON strings (-JsonString)
• Flexible Formatting: Supports all Format-Json formatting options including spaces/tabs indentation, custom indentation sizes, and compact output
• Pipeline Processing: Handles multiple objects via pipeline (last object overwrites when using same path)
• File System Management: Automatically creates directories as needed and handles file overwrites with -Force parameter
• PowerShell Integration: Full support for -WhatIf, various text encodings, and custom serialization depth

Usage Examples

# Export a PowerShell object with custom formatting
$config = @{ server = 'localhost'; port = 8080; ssl = $true }
Export-Json -InputObject $config -Path 'config.json' -IndentationType Spaces -IndentationSize 2

# Export JSON string in compact format
Export-Json -JsonString '{"name":"test","value":123}' -Path 'data.json' -Compact

# Pipeline export (last object overwrites previous)
@($obj1, $obj2, $obj3) | Export-Json -Path 'output.json' -IndentationType Tabs

Integration with Existing Functions

The function integrates seamlessly with existing module functions:

# Complete roundtrip workflow
$data = Import-Json -Path 'input.json'
$formatted = Format-Json -InputObject $data -IndentationType Tabs
Export-Json -JsonString $formatted -Path 'output.json'

Testing

Added comprehensive test coverage with 12 test cases covering:

• Basic object and JSON string exports
• All formatting options (spaces, tabs, compact)
• Pipeline processing behavior
• File system operations and error handling
• Integration with Import-Json for roundtrip validation
• Edge cases and error scenarios

All tests pass, and the implementation follows the established patterns and conventions used by Format-Json and Import-Json.

Fixes #3.

Expected $null or empty, because the script should use '$null = ...' instead of '... | Out-Nul...

Fixed the linting issue by replacing | Out-Null with $null = ... pattern on line 119. The functionality remains unchanged and directory creation works correctly. (1f501f1)

Fixed all linting issues:

• Removed trailing whitespace from 37 lines in Json.Tests.ps1
• Aligned assignment statements in General.ps1 examples
• Fixed close brace placement in Export-Json.ps1 catch blocks

All PowerShell files now pass syntax validation and follow proper formatting standards. (9d0633d)

Correct the tests for Format-Json to expect indents x 2 spaces by default, instead of 4.

[Copilot]

Correct the tests for Format-Json to expect indents x 2 spaces by default, instead of 4.

Updated the Format-Json test data to use 2-space indentation instead of 4-space to match the new default IndentationSize. The $prettyJson test data in the BeforeAll section now correctly uses 2-space indentation, ensuring consistency with the updated default parameter value. All tests are now passing. (0272237)
