fix(watch): re-glob entry files on create/delete events

sxzz · sxzz · commit a1969f7ade34 · 2026-02-27T19:49:20.000+09:00
When entry uses glob patterns like `src/**/*.ts`, new files added during watch mode now trigger a restart by re-resolving the entry globs on file create/delete events. Closes #709
