Adds 40 ScalarFunction registrations for tnumber-vs-{numspan, tbox,
tnumber} value-position predicates, backed by 20 wrapper functions:
4 ops (<<, >>, &<, &>) × 5 type-pair shapes:
tnumber × numspan, numspan × tnumber (intspan↔tint, floatspan↔tfloat)
tnumber × tbox, tbox × tnumber (both base types)
tnumber × tnumber (same base type only)
MEOS bindings (20):
left/right/overleft/overright_tnumber_numspan
left/right/overleft/overright_numspan_tnumber
left/right/overleft/overright_tnumber_tbox
left/right/overleft/overright_tbox_tnumber
left/right/overleft/overright_tnumber_tnumber
Implementation uses the TempBoxBoolPred / BoxTempBoolPred /
TempTempBoolPred helpers from PR #37 plus three new macros
(DEFINE_NUMSPAN_POS, DEFINE_TBOX_POS, DEFINE_TNUM_POS) that
generate the wrappers.
Smoke test:
SELECT tint '[1@01-01, 5@01-05]' << intspan '[10, 20]'; -- true
SELECT intspan '[10, 20]' >> tint '[1@01-01, 5@01-05]'; -- true
SELECT tfloat '[1@01-01, 5@01-05]' &< floatspan '[6, 10]'; -- true
SELECT tint '[1@01-01, 5@01-05]' << tbox 'TBOXINT XT([10,20],...)'; -- true
SELECT tint '[1@01-01, 5@01-05]' << tint '[10@01-01, 20@01-05]'; -- true
Stacked on PR #37 (tnumber × {numspan, tbox} topological).
Full suite passes (747 assertions, 13 test cases).

Consolidated into #40 (tnumber × {numspan, tbox} bounding-box predicates — topo + position combined). |
