Add version catalog flag and interactive setup option for new projects

[StephenBrough]

Added a --version-catalog flag to the new command. Also added a checkbox as part of the interactive setup.

Adding dependencies to an existing project with the version catalog appears to still work as well.

Walkthrough

This PR introduces a new VersionCatalog boolean feature across the application. It adds a command-line flag, CLI argument processing, interactive UI checkbox, state management, project generation parameter, and internationalization support for using Gradle version catalog dependency management.

Changes

Cohort / File(s)	Summary
CLI Flag Processing internal/app/cli/processing.go	Adds VersionCatalog Flag constant, bool field to Input struct, and entries to AllFlagsSpec and commandFlagSpec for the NewCommand. Updates ProcessArgs to parse and propagate the flag.
Command Execution cmd/ktor/main.go, internal/app/cli/command/generate.go	Updates Generate function signatures to accept versionCatalog bool parameter (inserted after plugins argument) and passes it through to project generation.
Project Generation internal/app/generate/project.go	Extends Project function signature with versionCatalog bool parameter; constructs versionCatalogValue payload and replaces hard-coded empty string for network.VersionCatalogBuildArg in BuildSystemArgs.
Internationalization internal/app/i18n/messages.go, internal/app/i18n/bundle.en.go	Adds VersionCatalogCaption and VersionCatalogOptionDescr message constants and English translations.
Interactive UI — State & Drawing internal/app/interactive/draw/state.go, internal/app/interactive/draw/tui.go	Introduces VersionCatalogCheckbox enum member to Element type; adds UI rendering for checkbox with label, styles, and layout positioning after location input. Note: NewState() initialization maps (CursorOffs, VisibleOffs, InputLens) may not include entries for the new checkbox.
Interactive UI — Event Handling & State internal/app/interactive/entry.go, internal/app/interactive/model/state.go	Adds event handling for VersionCatalogCheckbox (space key toggles, Enter key toggles), restructures navigation logic to handle the checkbox without PluginsShown gating, and adds VersionCatalog bool field to Result struct. Propagates VersionCatalog value to generateProject result.

⚠️ Potential issue | 🟡 Minor

Enter on the VersionCatalog checkbox doesn’t advance.

The early return means users can’t continue with Enter and must use Tab, which breaks the otherwise “Enter-to-advance” flow. If advancing is intended, drop the return to let the subsequent switch set PluginsShown and move focus.

🛠️ Suggested tweak

case draw.VersionCatalogCheckbox:
    mdl.VersionCatalog = !mdl.VersionCatalog
-   return
