263fc4b435 spvedit.py: drop the sentinel value check (the wrapper owns the sentinel); test the element-type check with a float3 array of the sentinel length

72af377a05 build-glsl.sh: the length-in-expression refusal test spells the sentinel in hex, which dxc keeps as the capacity constant

7416e8a775 glsl build: the capacity constant carries CultMath's own SpecId, so a consumer's SPIRV_CROSS_CONSTANT_ID_0 cannot clash 
SPIRV-Cross names the macro from the SpecId and offers no option to rename it, so the SpecId is CultMath's own
('CMS1'); partition.py reads it from spvedit.py.

ae838b60fd glsl build: the capacity edit names the site arrays by a sentinel length, with tests for the tool refusals 
wrappers.py compiles the library with CULTMATH_MAX_SITES defined as a sentinel no shader file spells, so the three
site arrays get an array length id of their own and spvedit.py converts exactly that constant to the overridable
specialization constant (default from the HLSL guard). A library array of literal length 128 keeps its own id and
stays a plain constant. build-glsl.sh gains the pipeline function and scratch variants: a macro outside a declarator,
a folded expression reaching the capacity id, and a non-site float4 x[128] parameter that a consumer's override must
not resize. The [128] shape arm goes: a non-site 128 array is legitimate output.

58baccce78 CultMathJson writes CultPhasor as cosine/sine and still reads cos/sin 
Fields takes an optional legacy name per field, matched on read only and mapped to the same index as the current name, so a legacy and a current name in one object are the same property and the duplicate rules decide (refused when AllowDuplicateProperties is false, last wins otherwise). Writing never emits a legacy name. MessagePack bytes are unchanged.

d605c70bba CultPhasor.cos/.sin become .cosine/.sine in C# and HLSL (GLSL regenerated next) 
SPIRV-Cross renames members matching GLSL builtins, so the source names change. Resolver and JSON writer accessors follow the members; the wire (positional MessagePack, JSON keys) is untouched in this commit. The committed GLSL is stale until its regeneration commit, so CommittedGlslEqualsLowering fails here.

150ea0a060 CultMath shaders: cultmath_power_border, cultmath_lattice_cell_distance and cultmath_weighted_lattice_cells over a fixed-capacity site array 
CULTMATH_MAX_SITES defaults to 128 under #ifndef. The consumer-written ring-loop and border-loop comment recipes are deleted. The C# mirror takes the array as T[]; the span twins live in SiteArrays; the GLSL lowering keeps the capacity macro; gen.py learns the array leaf; the smooth-step family gains its cap-point draw; CULTMATH_WRITE_GLSL refuses non-Linux.
