Introduce ClassicAPI.lua, a feature-detection layer for the ClassicAPI
client mod that mirrors NampowerAPI's HasMinimumVersion pattern
(IsAvailable / HasMinimumVersion / HasUnitAuras). UnitHasDispelType
scans a unit's auras via C_UnitAuras and reports the dispel type,
scanning debuffs or buffs based on a helpful flag.
Add conditionals backed by it:
- Debuff side (defensive cleanse): [magic] [curse] [disease] [poison]
[dispellable] + negations
- Buff side (offensive dispel/strip): [magicbuff] [dispellablebuff]
+ negations
All are no-arg booleans, default to @target (honor @unit), and degrade
gracefully without ClassicAPI: positive checks return false, negated
return true, since vanilla cannot read aura dispel types. The existing
ValidateAura path is untouched. MacroErrorChecker auto-accepts them via
the Keywords table; they're registered in BOOLEAN_CONDITIONALS so they
parse as flags. Loaded after NampowerAPI in the TOC.
Document opportunities to use ClassicAPI (modern C_* API backport for
the 1.12 client) in the addon: C_UnitAuras for target aura/dispel-type
conditionals, GetWeaponEnchantInfo enchant IDs for poison/imbue checks,
GetUnitSpeed to drop the MonkeySpeed dependency, plus C_Spell, C_Timer,
UnitGUID, native focus, and Tier-3 items.
Each entry cites API.md line refs and the addon files it touches, and
notes the cross-cutting requirement to feature-detect with fallback
(mirroring the nampower HasMinimumVersion pattern).
