Release karajo v0.9.1 (2024-04-06)

This release mostly contains chores.

* env: remove [rand.Seed] usage

  The [ascii.Random] generate random using "crypto/rand", so no need
  to seed it anymore.

* all: replace module "share" with "pakakeh.go"

  The "share" module repository has been moved to SourceHut, with new
  name "pakakeh.go".
