Alternative to #16425 Fixes #16585 Fixes #16389 Fixes #16252 Fixes #15794 Fixes #16646 Fixes #16358 This PR changes the Vite plugin to use the file-system to discover potential class names instead of relying on the module-graph. This comes after a lot of testing and various issue reports where builds that span different Vite instances were missing class names. Because we now scan for candidates using the file-system, we can also remove a lot of the bookkeeping necessary to make production builds and development builds work as we no longer have to change the resulting stylesheet based on the `transform` callbacks of other files that might happen later. This change comes at a small performance penalty that is noticeable especially on very large projects with many files to scan. However, we offset that change by fixing an issue that I found in the current Vite integration that did a needless rebuild of the whole Tailwind root whenever any source file changed. Because of how impactful this change is, I expect many normal to medium sized projects to actually see a performance improvement after these changes. Furthermore we do plan to continue to use the module-graph to further improve the performance in dev mode. ## Test plan - Added new integration tests with cases found across the issues above. - Manual testing by adding a local version of the Vite plugin to repos from the issue list above and the [tailwindcss playgrounds](https://github.com/philipp-spiess/tailwindcss-playgrounds).
