Implement ADR-0020: 2-pass data execution with greenlet kernel runner
Step 1 — Foundation:
- OpRecord/OpLogger: op log infrastructure with t_start stable ordering
- MemoryStore: numpy ndarray tensor-granular storage (reference semantics)
- data_op=True flag on DmaReadCmd, DmaWriteCmd, GemmCmd, MathCmd, CompositeCmd
- numpy/greenlet dependencies added to pyproject.toml
Step 2 — ComponentBase hooks:
- _on_process_start/end hooks in _forward_txn (fabric messages)
- _handle_with_hooks in PeEngineBase (PE-internal commands)
- op_logger optional — zero overhead when disabled
Step 3 — KernelRunner + greenlet:
- KernelRunner: greenlet ↔ SimPy bridge in triton_emu/kernel_runner.py
- TLContext: _emit() method routes to greenlet switch or command list
- tl.load() returns real numpy data in greenlet mode
- Dynamic control flow supported (memory-read based branching)
Step 4 — PE_CPU integration:
- Greenlet mode when ctx.memory_store is set, legacy fallback otherwise
- Refactored into _execute_greenlet/_execute_legacy/_send_response
- ComponentContext gains memory_store and op_logger fields
Step 5 — DataExecutor:
- Phase 2 numpy execution for GEMM/Math ops from op_log
- _compute_math: all unary/binary/reduction ops
- verify(): compare MemoryStore against expected with dtype tolerance
28 new tests, 366 total passing.

Add web topology viewer with hot path visualization
- FastAPI backend (server.py) with REST API + WebSocket for event streaming
- SVG-based topology viewer (index.html) with SIP/CUBE/PE drill-down views
- Event logging infrastructure (event_log.py) generating events from real
probe cases (H2D/D2H/PE-DMA) and bench workloads (QKV GEMM single/multi-PE)
- Timeline replay engine with play/pause, speed control, and scrubbing
- Workload selector dropdown grouped by category (Probe/Bench)
- CLI entry points: kernbench web, ./kernbench wrapper scripts
