ai.md + TASKS: record the LlamaCasty/ytLive naming split and the shipped-exe mismatch

Creator correction 2026-09-26: the product is LlamaCasty; ytLive is only the internal
repo/assembly/namespace name. Records the exact split (incl. the capital-L ytLlive app
data dir), the Distribution.md LlamaCasty.exe vs real ytLive.exe mismatch, and the three
pack URIs that hardcode the assembly name -- MainWindow.xaml:14 is the window icon, so a
naive AssemblyName rename ships a broken taskbar icon. Notes the app-data rename is
breaking and that no code compares its own assembly name.

      conflicts with the obfuscation posture in `Distribution.md` §1.2.

+     taskbar/Alt-Tab icon). Namespaces stay `ytLive.*`; the 230-file re-brand is NOT
+     wanted. Do **NOT** touch the `%APPDATA%\ytLlive` folder — breaking (orphans users'
+     layout DB). See the naming table in `ai.md`.
   Do **NOT** add `-p:PublishTrimmed=true`: WPF is not trim-compatible and it fails at
   runtime (BAML/XAML resource resolution), not at build time. `PublishReadyToRun` is safe.
