Describe the bug
While using syncthing to sync obsidian vault across devices, the quartz server crashes.

Error: ENOENT: no such file or directory, copyfile 'content/.syncthing.index.md.tmp' -> 'public/.syncthing.index.md.tmp'

    at Object.copyFile (node:internal/fs/promises:623:10)

    at copyFile (../plugins/emitters/assets.ts:24:3)

    at partialEmit (../plugins/emitters/assets.ts:43:11)

    at rebuild (../build.ts:275:24)

I have tried including patterns like **/*.tmp and *.tmp in ignorePatterns, but that doesn't seem to work.

To Reproduce
Steps to reproduce the behavior:

1. Sync the vault with Syncthing
2. Make changes in any of the files

Expected behavior
If a file is not found, it should be ignored or a corresponding log should be shown

Or, if the file which was not found matches one of the ignore patterns, dont throw the error
