Release 1.1.0

[emir-hasanbegovic]

Version bump for the pending work on main:

• Added: configurable keep-awake (Power settings)
• Fixed: zero-width overflow menus, cross-transport twin dedup, pinned Configure-binding action bar
• Changed: app-mark iconography; release pipeline moved to the shared harden workflow with advisory Authenticode signing (feat(release): shared harden (grype, SBOMs, cosign, SLSA) + advisory Authenticode signing #54) and a from-source SLSA generator (fix(release): compile the SLSA generator from source #55)

CHANGELOG heading dated, and all three version mirrors (CMakeLists.txt, packaging/dish.rc, vcpkg.json) move together so version-consistency.yml and the tag-build asserts pass. Tagging 1.1.0 after merge publishes it.

No changes to the stable asset names (dish-setup.exe, dish-windows.zip, latest.json) — this repo is already the model the other product repos just adopted.
