chore: minor bugfixes

[Kvadratni]

This pull request includes several changes to improve the Goose IntelliJ plugin by refactoring utility methods and updating the startup activity and profile selection logic. The most important changes include adding new utility methods for fetching available providers and toolkits, refactoring the startup activity to use these new methods, and simplifying the profile selection logic.

Refactoring and Utility Methods:

• Added methods GooseUtils.getAvailableProviders and GooseUtils.getToolkitsWithDescriptions to fetch available providers and toolkits with descriptions. (src/main/kotlin/com/block/gooseintellij/utils/GooseUtils.kt) [1] [2] [3]

Startup Activity Improvements:

• Updated GoosePluginStartupActivity to use the new utility methods GooseUtils.getAvailableProviders and GooseUtils.getToolkitsWithDescriptions. (src/main/kotlin/com/block/gooseintellij/actions/GoosePluginStartupActivity.kt) [1] [2]

Profile Selection Simplification:

• Simplified SelectGooseProfileAction by removing the redundant getAvailableProviders method and using GooseUtils.getAvailableProviders instead. (src/main/kotlin/com/block/gooseintellij/actions/SelectGooseProfileAction.kt) [1] [2]
• Replaced inline logic for fetching toolkits with descriptions with GooseUtils.getToolkitsWithDescriptions in SelectGooseProfileAction. (src/main/kotlin/com/block/gooseintellij/actions/SelectGooseProfileAction.kt) [1] [2] [3]

Code Cleanup:

• Refactored GooseUtils.startGooseSession to remove the usingSqGoose parameter and determine the Goose instance internally. (src/main/kotlin/com/block/gooseintellij/utils/GooseUtils.kt) [1] [2]
• Improved readability by reformatting code blocks in SelectGooseProfileAction. (src/main/kotlin/com/block/gooseintellij/actions/SelectGooseProfileAction.kt) [1] [2]
