Valorian UI

Key Architectural Upgrades:

 - Eliminated ephemeral table allocations by replacing `ipairs({ ... })` with native `select()` traversals in all high-frequency `OnUpdate` and event loops.

 - Secured the "Black Hole" UI vacuum by detaching dummy frames from `UIParent` to prevent secure execution taint during combat lock-down.

 - Unrolled static array tables (e.g., Objective Tracker buttons, MicroButtons, Visibility Watchdog) into file-scoped local closures to prevent continuous memory reallocation.

 - Bypassed the Lua `_G` lookup penalty by localizing high-frequency native Blizzard API calls.
