Brandon Schneider 2a2aa0535f feat(pist): remove dead PISTMachine root; add Trace tactic module
lakefile.toml (PIST lib roots):
- Remove "PISTMachine" — PISTMachine.lean does not exist; dead root
  would cause lake build PIST to fail with "unknown module" error
- "Trace" was already added in the prior dirty change; committed here
  paired with the file it requires

2-Search-Space/PIST/Trace.lean (new):
- Lean 4 tactic `trace_state_json "tag"` for Tier 2 flexure recording
- Emits structured goal-state JSON (target, hypotheses, goal_count)
  prefixed with @@PIST_TRACE_JSON@@ sentinel to logInfo stdout
- Python trace bridge parses the sentinel to capture mid-proof state
- Namespace: PIST.Trace; no sorry, no float, no external deps beyond Lean
