Closes #48

Adds nine cmdlets that wrap the Fabric Git REST APIs, following the design agreed in #48 (comment).

API	Cmdlet
Connect	Connect-FabricGit
Disconnect	Disconnect-FabricGit
Get Connection	Get-FabricGitConnection
Initialize Connection	Initialize-FabricGitConnection
Get Status	Get-FabricGitStatus
Commit To Git	Invoke-FabricGitCommit
Update From Git	Invoke-FabricGitUpdate
Get My Git Credentials	Get-FabricGitCredential
Update My Git Credentials	Update-FabricGitCredential

Design decisions applied

• Provider type: -GitProviderType is mandatory on Connect-FabricGit. It must match the parameter set used: Azure DevOps needs -OrganizationName/-ProjectName, GitHub needs -OwnerName. If they don't match, the cmdlet throws a clear error before calling the API. GitHub also requires -ConnectionId.
• Connect and initialize together: Connect-FabricGit -Initialize [-InitializationStrategy] [-NoWait] connects and initializes in one call. Initialize-FabricGitConnection is still available for workspaces that are already connected.
• Automatic lookup: if you don't pass WorkspaceHead or RemoteCommitHash, Invoke-FabricGitCommit and Invoke-FabricGitUpdate get them from Get-FabricGitStatus. -NoAutoResolve turns this off.

Other behaviour

• Pipeline input: every cmdlet takes WorkspaceId from the pipeline by property name (alias Id), so Get-FabricWorkspace | Get-FabricGitStatus works.
• Status output: Get-FabricGitStatus -ChangesOnly / -ConflictsOnly returns one flat object per changed item. You can filter these and pipe them into Invoke-FabricGitCommit, which commits the selected items in a single API call per workspace.
• Confirmation: all cmdlets that change state support -WhatIf/-Confirm. Disconnect-FabricGit and Invoke-FabricGitUpdate use ConfirmImpact = 'High'.
• API calls and errors: all calls go through Invoke-FabricRestMethod with hash splatting and HandleResponse = $true, which handles long-running operations and throttling. API errors are thrown rather than swallowed.

Example

$ws = (Get-FabricWorkspace -WorkspaceName 'Sales').id
$init = Connect-FabricGit -WorkspaceId $ws -GitProviderType AzureDevOps -OrganizationName 'contoso' `
    -ProjectName 'Fabric' -RepositoryName 'sales' -BranchName 'main' -Initialize -InitializationStrategy PreferRemote
if ($init.requiredAction -eq 'UpdateFromGit') { Invoke-FabricGitUpdate -WorkspaceId $ws -Confirm:$false }

Get-FabricGitStatus -WorkspaceId $ws -ChangesOnly |
    Where-Object ItemType -eq 'Notebook' |
    Invoke-FabricGitCommit -Comment 'Notebooks only'

Testing

• 90 new unit tests (one file per cmdlet in tests/Unit/). They cover request URIs, methods, bodies, parameter sets, pipeline binding, -WhatIf, automatic lookup and -NoAutoResolve, and error paths. All pass.
• The full unit suite and the QA suite (tests/QA) pass with no failures.
• Not yet tested against a live Fabric workspace. The request bodies follow the Fabric Git API documentation, so a manual run of connect → initialize → status → commit/update is recommended before merging.

Docs

• Nine new help pages were generated with Generate_help_from_built_module, and the cmdlets were added to docs/en-US/FabricTools.md.
• The generator also rewrote about 200 unrelated help pages (date changes and differences from their source). Those changes are left out of this PR on purpose.
• CHANGELOG.md has an entry under [Unreleased] / Added.
