New selection_strategy='lookahead' with depth-limited recursive
future gain estimation using the partial model. Adds simulate_action()
for pessimistic transition simulation and BoundedLookaheadSelector.

Bump version to 0.3.0. Update roadmap with phased MCTS plan.
IGMCTSSelector with UCT selection, expansion, greedy rollout, and
backpropagation. Registered as selection_strategy='mcts' with
configurable iterations and rollout depth.
Deduplicate the ~40-line injective binding filter block that was
copy-pasted between sequential and parallel gain computation paths.
- Add action_model_metrics statistics to intermediate model snapshots
- Remove mistake_rate from summary stats (keep in per-snapshot data)
- Add aggregated statistics and per-action metrics to summary.json
- Remove statistics from learned_model.json (now in summary.json)
- Simplify output file names to summary.json, metrics.json, metrics.csv
- Add timestamp marker file to problem directory
