v1.6.0 - your priority list + action-bar highlight

Two things: the rotation now follows YOUR authoritative priority list verbatim, and the recommended ability is highlighted on your action bar.

PRIORITY LIST (replaces everything we derived):
Roll the Bones below Stage 2 -> Keep It Rolling at Stage 2+ -> Adrenaline Rush at low CP -> Blade Rush as a builder -> Between the Eyes at 6+ CP -> Preparation to reset AR/BtE/Blade Rush -> Killing Spree at 6+ CP -> Dispatch at 6+ CP when no other finisher is up -> Pistol Shot (6 stacks any CP, 3-5 stacks only at 1-3 CP) -> Sinister Strike.
Blade Flurry is now the ONLY single-target/AoE difference, fired at 2+ targets and preferring low combo points for Deft Maneuvers. The separate AoE priority list is deleted.
NOTE: Dispatch is a 6+ CP finisher, so at 5 CP the bar correctly shows a builder first, then the finisher - that is the list working, not a stuck icon.

ACTION-BAR HIGHLIGHT (/oa glow):
The position-1 recommendation is glowed on your real action bar. It probes Blizzard glow helpers first, then any discoverable action-bar API, and falls back to a self-drawn overlay so it never silently does nothing. Exactly one button glows at a time. /oa glow toggles it, /oa glow combat makes it combat-only, and /oa debug reports the resolved slot, the button frame, and which glow mechanism is active.

HONEST GAPS:

• Killing Spree Supercharger exception NOT implemented: the buff spell ID could not be verified from a live source, so the rule ships without that condition rather than with an invented ID.
• Opportunity now tracks stack counts, which rule 9 needs; verify in-game that stacks read correctly.
