Enhance Foundry with expert configuration and UI improvements

[mchave3]

This pull request establishes the groundwork for supporting Standard and Expert configuration modes in the Foundry project, focusing on requirements gathering, technical planning, and initial code changes for future deploy-side configuration extensibility. It introduces detailed planning and progress documentation, updates the deploy UI for future expert-mode integration, and adds initial deploy configuration models for customization and localization.

The most important changes are:

Documentation and Planning

• Added findings.md and progress.md files that capture requirements, research findings, technical decisions, architecture drafts, implementation order, and session-by-session progress logs. These documents will guide the implementation of Standard/Expert modes, import/export, and deploy integration. [1] [2]

Deploy UI Preparation

• Updated MainWindow.xaml in Foundry.Deploy to bind the computer name textbox's read-only state and the language selection combo box's enabled state to new view model properties, paving the way for expert-mode-driven UI behavior. [1] [2]
• Updated event handlers in MainWindow.xaml.cs to respect the read-only state for the computer name textbox, preventing editing or pasting when the field is locked by configuration. [1] [2]

Deploy Configuration Models

• Added new configuration models: DeployCustomizationSettings and DeployLocalizationSettings in Foundry.Deploy.Models.Configuration. These records will represent customization and localization settings (such as machine naming and language visibility/selection) as part of the upcoming expert deploy configuration contract. [1] [2]
