Add [totem] and [nototem] conditionals

A totem is a summoned creature, not an aura, so nothing in the addon could see
one. Strength of Earth and Mana Spring could be faked through [nomybuff], but
Searing, Magma, Fire Nova, Tremor and Grounding put nothing on the player at
all, and those are the ones worth conditioning a recast on. There was no
workaround.

ClassicAPI backports the TBC totem bar (src/totem/Tracker.cpp), tracking the
player's own summons from their SMSG_SPELL_GO and classifying them by the
summon spell's SUMMON_TOTEM_SLOT1..4 effect, so Turtle's custom totems
self-classify. Ungated like GLOBAL_MOUSE_*: the tracker landed in v1.10.0, far
below the v1.15.0 floor the addon already refuses to run below.

[totem:X] takes an element (fire/earth/water/air), a slot number, or the totem's
own name -- ResolveTotemSlot tries the slot table first, then matches X against
the name standing in each slot, so [totem:Searing_Totem] asks for that totem
rather than whatever holds the fire slot. Bare [totem] takes the action as its
argument the way [mybuff] does, making /cast [nototem] Searing Totem a complete
recast macro.

Comparisons follow the aura precedent exactly: an empty slot reads -1, the same
"missing counts as least" ValidateAura uses, so [totem:Searing_Totem<5] passes
while the totem is expiring AND while it is absent -- one clause, no [nototem]
needed. A totem is either up or it isn't, so #N stack comparisons read 1 for a
standing totem. The parser needed nothing: its name/operator/amount capture is
generic, so multi-comparisons ([totem:X>2&<8]), OR groups and the De Morgan
flip all came for free.

Occupancy is read from GetTotemInfo's totemName, never from the time left.
GetTotemInfo's first return is TOOL presence -- whether the player carries the
slot's Earth/Fire/Water/Air Totem item -- not whether a totem is out, and a
summon spell with no SpellDuration row reports 0 seconds, which is "up with no
timer", not "absent".

Icon refresh needs two feeds. PLAYER_TOTEM_UPDATE covers a slot changing hands
(dropped, expired, killed, recalled). It does not fire as a totem counts toward
zero, and unlike an aura there is no ambient event stream to ride -- UNIT_AURA
is what quietly keeps [mybuff:X<N] honest -- so a [totem:X<N] icon held its last
answer until some unrelated event queued a refresh: the macro sat on the
question mark through the window it should have lit up. Hence the once-a-second
re-test in OnUpdate while any totem timer runs, skipped in realtime mode, which
re-tests everything anyway. Only the icon was ever at stake; the click path
evaluates conditionals live.
