Description

Current Behavior
Even when passing only 1-2 changed files as entryPoints, unplugin-dts still performs full type analysis of the entire codebase, taking the same time as a complete rebuild (~8-10 seconds).

Expected Behavior
When only specific files are provided as entry points, the plugin should:

• Analyze only the changed files and their direct dependencies
• Skip unchanged files that were previously processed

Suggested solution

Implement a build cache mechanism similar to TypeScript's .tsbuildinfo to enable true incremental builds.
