Crate axiolid

Feature-gated facade for Axiolid geometry.

Nothing is compiled unless it is asked for: default = [], so a consumer names the capability they need and pays for that alone (kernel#9). Building with no feature at all raises a compile_error! listing the options rather than leaving an empty crate whose every call site fails as “not found”. standard reproduces the pre-0.4 default (mesh + cpu + integration) for consumers who want the old behaviour in one line.

Features are additive and named for geometry capabilities. No feature or bundle is named after a source format, vendor or downstream product, and every package behind a feature stays usable as a direct dependency.

Exact geometry is the primary currency

No entry point in this facade converts exact geometry into a mesh unless the caller asked for one and supplied a tolerance. Tessellation is a requested OUTPUT, never a fallback:

• generate::GenerationRequest::ExactBRep carries no tolerance field, so a mesh cannot be produced for it. A request it cannot satisfy exactly is refused rather than approximated.
• generate::TessellationRequest and TessellationOptions have no Default. There is no global chord error to fall back to, because acceptable error depends on source units and downstream use.
• A tessellated result carries the tolerance it was built to, so an approximation cannot later be mistaken for an exact value.

tests/exact_primary.rs holds this to account (kernel#36).
