Release awwan v0.12.1 (2024-04-05)

This release replace module "share" with "pakakeh.go".

In the "_wui", we use shared static assets from Cloud Storage.
The idea is to minimize noise in the logs that does not related to page
access and minimize binary size.

In the "_ops", we use shared mkosi cache in user’s home ".cache".
This is to minimize duplicate files and allow us to find or grep files
without excluding certains directory.

We also apply some recommendations from linters.
