v24: Resolve GitHub Issues #1-#5

Issue #1 — Winner's life total now captured:
  - Parse verbose Forge log for life-total-change events
  - Track last-known life per seat via 3 regex patterns
  - Winner's final life set from log data (not left at default 40)
  - Losers who died to mill/poison retain their actual life total

Issue #2 — Win condition classification formalized:
  - New WinCondition enum (schema/WinCondition.java) with 8 categories
  - Centralized Forge loss-reason-string → enum mapping (regex-based)
  - UNKNOWN fallback with logging for unrecognized loss reasons
  - All classification now goes through WinCondition.classify()

Issue #3 — JVM startup overhead reduced:
  - Added -XX:+UseSerialGC (lighter GC for batch processes)
  - Added -XX:TieredStopAtLevel=1 (faster JIT, less compilation)
  - ForgeWorker stub class for future persistent batch mode
  - Estimated reduction: ~2-3s → ~1-1.5s per game startup

Issue #4 — Single-threaded throughput optimization:
  - New CLI flags: --ai-simplified, --ai-think-time, --benchmark
  - JVM flags passed through to Forge subprocess
  - Benchmark mode: run 1 game before batch, report wall/Forge/overhead times
  - API support: aiSimplified, aiThinkTimeMs in StartRequest

Issue #5 — Threading, progress, and backpressure:
  - --threads 0 or -1 auto-detects optimal count from CPU topology
  - detectOptimalThreads() estimates physical cores (excludes HT)
  - ProgressCallback interface for real-time sims/sec reporting
  - Per-game progress emitted as [PROGRESS] lines, parsed by lab_api.py
  - --max-queue flag for graceful backpressure (limits concurrent JVMs)
  - Final throughput summary printed at batch completion
  - StatusResponse now includes simsPerSec field

Also: .gitignore restored, lab_api.py updated with all new API fields
