v0.1.6

• Added explicit verified baseline and optimized compilation levels for latency-sensitive frontends.
• Added live tier management with hotness profiles, single-compiler claims, immutable generation switching, retry, and withdrawal.
• Added concurrent runtime assumptions, quiescent invalidation, cache retirement, and ThreadSanitizer qualification.
• Added immutable deoptimization records and exact Float64 guard-value recovery on all three native backends.
• Added checked PocketPy division with validated ZeroDivisionError reconstruction.
• Added overflow-safe eight-way Lua loop unrolling and promoted the Lua/LuaJIT result to a commercial CI gate.
• Added deterministic differential fuzzing, concurrent code-cache stress, retained records, and dedicated stress workflows.
• Added machine-readable performance gates for Lua, QuickJS, PocketPy, LuaJIT, V8, and CPython comparison targets.
• Added a bounded generation-aware LRU native-code cache and exact-source reuse in all three frontends.
• Added complete QuickJS and PocketPy numeric counted-loop compilation with CFG safepoints and benchmark gates.
• Added typed Float64 CFG values, arithmetic, comparisons, edge validation, interpretation, and three-backend lowering.
• Fixed CFG context metadata and parallel edge copies for shared physical registers.
