libspell.GetSpellInfo now returns the spell ID at position 9 and caches
it with SafePack and unpack.
The action bar tracks self.spellID for macro-cast spells and shows the
tooltip with GameTooltip:SetSpellByID. Gather the slot, book type, and
spell ID from one GetSpellInfo call instead of a separate GetSpellIndex
lookup.
Clear existing spell cache tables with table.wipe instead of creating new tables when LEARNED_SPELL_IN_TAB fires. This preserves existing table references (spellmaxrank, spellindex, spellinfo), avoiding stale references and potential bugs while being slightly more efficient. Change applied in libs/libspell.lua.
GetSpellInfo internals now delegate to ClassicAPI's GetSpellInfo for the
DBC metadata read instead of scraping castTime/range out of the tooltip.
Drops the libtipscan dependency from libspell and the regex-based parsing
of SPELL_CAST_TIME_SEC/MIN/SPELL_RANGE. Same 8-value return shape so all
call sites (libtotem, libpredict, libcast, actionbar) continue working.
