Add Personal Access Token management and Oh-My-Posh integration

[igoravl]

• Update RELEASENOTES.md to replace incorrect -AsAdmin mode references with the actual -User parameter for Get-TfsPersonalAccessToken and Remove-TfsPersonalAccessToken
• Fix build error in RemovePersonalAccessToken.cs (extra { from bad reviewer suggestion in commit 8a2f0b0)
• Project SessionToken → PatToken in admin path of GetPersonalAccessToken.cs to ensure consistent OutputType = typeof(PatToken) across all parameter sets; added unit test
• Fix AGENTS.md Controllers section, Project structure, and "Adding a new cmdlet" steps to correctly reflect that controllers are partial classes in the same file as their cmdlet under CSharp/TfsCmdlets/Cmdlets/{Domain}/
• Fix Get-TfsPersonalAccessToken returning no results: ListPats now passes null for unspecified optional filter parameters (DisplayFilter, SortBy, IsSortAscending) so the API uses server-side defaults instead of potentially mismatched C# enum zero-values; added null guard for PatTokens
• Fix Docs/ARCHITECTURE.md project structure tree: remove non-existent Controllers/ directory under CSharp/TfsCmdlets/, move ControllerBase.cs inside Cmdlets/ where it actually lives, and correct TfsCmdlets.Legacy/ layout
• Refactor CurrentConnectionsImpl.Set() overloads to avoid redundant SyncEnvironmentVariables() calls — each overload now assigns all fields directly instead of chaining, so env vars are synced exactly once per call

Changes:

• Introduces Get/New/Set/Update/Remove-TfsPersonalAccessToken cmdlets (including Token Admin support for other-user operations) and unit tests.
• Adds Oh-My-Posh integration to Enter-TfsShell with a bundled theme and opt-out/custom-theme switches.
• Synchronizes connection state to TFSCMDLETS_* process environment variables and clears them on module unload.
