[Feature Request] Near-real-time index update for external drives

[mono0x]

In my understanding, currently, Cling indexes external volumes periodically using fd command. This mechanism has a delay depending on the interval. On the other hand, updates of the internal volume are reflected near-real-time thanks to the FS Events API.

Could it be possible to apply the same mechanism for external volumes if the file system is supported? I would like to have the same experience as the internal drive through external drives because I use external SSDs and HDDs for my main workspace.
