Axioval 0.1.0

Added

• Initial source-neutral engine workspace and architecture contract.
• Fail-closed runtime registry-drift and duplicate package rejection.
• Dependency-policy, canonical snapshot identity, and workspace package-verification gates.
• Exact source-neutral connectivity graphs with deterministic width-constrained traversal.
• Backend-neutral metric-routing requests, bounded shortest-distance evidence, and request-bound blocked verdicts.
• Backend-neutral free-area, directional-clearance, and constrained placement-search evidence contracts.
• Complete walkable-region snapshots with deterministic three-valued width-constrained routing.
• Explicit deterministic report outcomes for missing services, backend outages, incomplete/invalid evidence, and resource limits.
• Exact grounded free-floor circle and rectangle capabilities backed by the source-neutral free-space service.
• Exact property-to-property comparison capability slice with independent candidate selectors, request-bound relationship selection, target factors, each / at_least_one, and evidence-backed missing-information behavior.
• Exact request-bound property resolution for both present values and conclusive absence evidence, including cross-object substitution rejection, finite numeric validation, and fail-closed property selector evaluation.
• Source-neutral canonical SI quantity dimensions, boxed selector-valued parameters, and exact relationship-selection requests bound to a checked object and complete candidate universe.

Fixed

• Placement offset bounds no longer admit tolerance-expanded witnesses; supported found placements now require exact frame-bound whole-base support evidence.
