RUE-1033: Remove the query compatibility graph

[steveklabnik]

Summary

• remove the retired ADR-0050 semantic manifest/invalidation machinery and durable body/CFG import caches
• delete the peer QueryGraph, selected-state TypedQueryStore caches, leaf stores, and the parse RevisionedFamily shim
• make whole-program, import, diagnostics, and tooling views thin projections of the canonical revisioned query runtime
• make each canonical semantic output retain its exact RIR owner, preventing interner mismatches across codegen, linking, presentation, and oracle consumers
• add structural gates for a one-function warm edit through one replacement CodegenUnit and a fresh runnable link, plus byte-identical one-worker/four-worker executables
• supersede ADR-0050 and record the remaining Phase 12 memory-budget decision in RUE-1210

No language semantics change is intended. Diagnostic lifecycle and current/last-good behavior now come from the canonical runtime rather than the removed peer cache.

ADR-0063 Phase 12 remains unchecked: deterministic cross-family retained-byte and dependency-lease budgeting requires the policy decision and enforcement tracked separately.
