fix(swc): fix inverted chokidar ignored filter in watch mode

The ignored callback in watchFilesInSrcDir had two layered bugs:
1. Extension format mismatch: the extensions array contains dotted
   extensions (.ts) but the comparison stripped the dot, so the
   filter never matched any files.
2. Inverted logic: the filter ignored files that matched source
   extensions instead of ignoring files that don't match.

The net effect was that all files in the source directory triggered
the watcher, causing unnecessary recompilation for non-source
files like .json, .css, or .env.

Fix by using file.endsWith(ext) for robust matching and negating
the condition to properly ignore non-source files.
