release: v0.1.1

Bump package + crate + tauri identifier from 0.1.0 to 0.1.1 and
rebuild the .deb. The 0.1.1 binary includes everything between
fork-init and HEAD~0:
  - custom TCP/QUIC listen ports (default 9651/9652)
  - daemon-failure banner with shortcut to Settings
  - misc UX wording

CHANGELOG split: 0.1.1 section closes the previously-Unreleased
list; 0.1.0 untouched.

release/mycellium-ui-private_0.1.0_amd64.deb removed and replaced
by 0.1.1 with refreshed SHA256SUMS.
