Necromancer's Pet Frames Optimized (ConquestReborn)

Original Project Name: Necromancer's Pet Frames (ArdenWoW).
Optimized mod from the original mod created by @Smollett.

Many bugs on original version where summon could be stuck in HUD or disappear with no reason.

This version optimise the code to fix all sync / refresh problems. 

Changes from the original addon to version 0.5:

• Combat updates: minion rows can appear, update and disappear during combat.
• Accurate health: removed the invented 1,000 HP starting value. Health comes from actual unit readings; estimates are marked with ~.
• Automatic health reads: nearby minions can update through nameplates without requiring mouseover.
• Readable bars: health numbers appear above the bar, and long names stay on one line.
• Safer tracking: unrelated buff expiry and failed targeting no longer delete minions. Living-unit readings override conflicting buff or Life Force estimates.
• Army changes: added replacement tracking, dynamic summon capacity and handling for every installed rank of Sacrifice Undead.
• Individual targeting: identical summons now use separate unit references, checked again when clicked. Clicking remains available outside combat.
• Exit crash fix: removed unsafe nameplate access during shutdown.

Added commands:

• /nm refresh — rescan minions.
• /nm clear — clear stale entries and rescan.
• /nm autohealth on or off — toggle automatic health reads.
• /nm status — show tracking information.
• /nm trace — show recent removal reasons.
