Fixes #43

Summary

• Unified Loop Fuel Enforcement & Reporting (#43):
  • Aligned SliceIsolate::apply_boa_realm_runtime_limits (set_loop_iteration_limit(remaining_fuel)) and SliceIsolate::finish_boa_compartment_execution (consume_fuel(loop_iters)) to the exact same 1 fuel unit per 1 iteration scale, and moved apply_boa_realm_runtime_limits to run immediately before guest script evaluation (after cold-realm prelude/shard initialization).
  • Replaced CallFrame::loop_iteration_count (context.vm.frame_mut() heap dereference on every loop iteration) with inline RuntimeLimits::check_and_increment_loop_iteration() (next > self.loop_iteration), shrinking CallFrame by 8 bytes and eliminating off-by-one boundary drift.
  • Emitted IncrementLoopIteration after the loop exit branch in compile_while_loop, compile_for_in_loop, and compile_for_of_loop, and routed top-level while loops (in_function_depth == 0) to Boa's bytecode VM.
  • Verified exact reported fuelUsed == smallest budget that completes parity across for (4005 == 4005), while (1000010 == 1000010), and do-while (1000010 == 1000010).
• Full 33-Workload Benchmark Suite (v0.10.8):
  • Updated tests/reports/bench_v0.10.8_20261111_000408Z_8e712ae.md (33/33 faster than Deno & Node.js, 33/33 faster in --warm pooled execution, 172,255 req/s Tier-0 slice serve and 158,151 req/s Tier-1 WinterTC slice serve).
