Subject: [PATCH] Make the comparison families consistent camelCase
 (tempEq/everEq/alwaysEq)

The three comparison families now share one camelCase shape <prefix>{Eq,Ne,Lt,Le,
Gt,Ge}: temporal #= -> tempEq..., ever ?= -> everEq..., always %= -> alwaysEq... .

Previously #= was the lowercase teq/tne... and the ever/always families were listed
under alreadyCanonical (left as snake ever_*/always_*), i.e. with no portable bare
name at all. That violated the contract's own goal (every operator has its bare
name on every engine, no exclusions) and left the th3 prefilter predicate without a
portable name. Adds everComparison/alwaysComparison to families (6 operators each)
and drops the ever/always alreadyCanonical entries. Matches MobilityDB#1075's
generator (OP_TO_NAME) so every binding regenerates the same names.
