📝 Walkthrough

Walkthrough

The change prevents save-triggered Tailwind work without configured files, updates configuration reload scheduling and awaiting, and increments the extension version to 1.14.3.

Changes

Tailwind file-save behavior

Layer / File(s)	Summary
Asynchronous configuration reload src/Configuration/ConfigurationFileReloader.cs	Configuration imports use a case-insensitive comparer. File-save handling schedules asynchronous work, awaits semaphore access, and awaits distinct configuration reloads.
Configuration-dependent save operations src/Build/TailwindBuildProcess.cs, src/ClassSort/ClassSorter.cs	Build and class-sorting operations return when no Tailwind configuration file is configured.
1.14.3 release metadata CHANGELOG.md, src/source.extension.cs, src/source.extension.vsixmanifest	The changelog, version constant, and VSIX manifest report version 1.14.3.

Merge Risk: 🔵 Low · up to 5469a

Adding a configuration can repeat the full reload work, causing a bounded performance regression. The change remains low risk but should remove the duplicate reload.

from ConfigurationFileReloader.OnSettingsChangedAsync, since
ProjectConfigurationManager.OnSettingsChangedAsync already performs
ReloadCustomAttributesAsync(settings). Preserve the added computation, _settings
