using cool idea but imo very risky for something that could break with any patch |

Replaces the scaffolded stubs with the full cast-lifecycle
implementation. Debug output via DF:Debug("TARGETEDLIST", ...) is
used as a stand-in for visual bars until commit #5 lands the render
pipeline — this lets in-game verification happen against the debug
console without requiring the full rendering work first.
All 13 correctness gotchas from the TS3 cross-reference in
_Reference/targeted-spells-findings.md are handled and tagged inline:
#1 0.2s delay before reading cast data (start events fire before
UnitSpellTargetName / duration are populated)
#2 Cast-ID matching at both pickup (via UnitCastingInfo) and stop
(via event castGuid) — prevents rapid-restart flicker
#3 UNIT_SPELLCAST_SUCCEEDED during an active channel is treated
as a no-op (channel tick, not a stop)
#4 INTERRUPTED with nil interrupter or a dead caster is treated
as a normal stop (no interrupter flash)
#6 Empower spellId/castGuid offset handled (same shape as regular
start on current retail — documented inline)
#7 Interrupter lookup via UnitNameFromGUID / UnitClassFromGUID
#8 Uninterruptible flag from UnitCastingInfo/UnitChannelInfo is
treated as secret-tainted and only ever fed to
SetVertexColorFromBoolean (applied in commit #5)
#9 UNIT_SPELLCAST_INTERRUPTIBLE / NOT_INTERRUPTIBLE overwrite the
stored uninterruptible field with a clean boolean
#11 LOADING_SCREEN_DISABLED triggers a full release sweep
Also adds the cast-targeting filter pipeline:
* TargetedList_IsRelevantCaster filters out non-nameplate units,
friendly units, and party-member nameplates
* TargetedList_ReadCastData unifies UnitCastingInfo / UnitChannelInfo
read paths, handling the positional offset difference for
castID vs notInterruptible between the two APIs
* Important-spells filter via C_Spell.IsSpellImportant
* Hide-own-casts filter
* Roster name cache used for O(1) target lookup
Event dispatcher extended to route NAME_PLATE_UNIT_ADDED and
UNIT_TARGET through the start handler so new nameplates and mid-cast
target swaps are picked up. UNIT_TARGET also fires an immediate stop
to drop the old tracking — the 0.2s delayed re-pickup recreates it
if the new target is still a party member.
Content-type filter (gotcha #13) is intentionally deferred to
commit #5 since the existing TargetedSpells content-type detection
can be reused rather than duplicated.

… inside the button subtree onUpdateMode=disabled propagates through the whole subtree, so an OnUpdate/ AnimationGroup on a button descendant installs but never ticks. The prior note claimed the opposite (the probe only checked SetScript/Play don't error). Point to the external-driver pattern (DF.Border ensureDriver, secretRect -> UIParent).

Summary
Adds a Health Threshold Fading option: frames or elements can be faded when a unit's health is above a configurable threshold (e.g. 100% or 80%). This helps highlight damaged units and reduce visual clutter from full-health ones.
