fix(simulation): address PR #37 re-review — stale strings, test coverage, confrontation symmetry

Hoshe re-review (3 items):
- content_scaling.rs:185: doc "StableId 0-51" → references constant
- content_scaling.rs:256: assertion message "id<=51" → "id <= max_baseline_id"
- input.rs: teleport test now asserts WalkAwayRequest + ConfrontationDelivered
  are cleared (was only checking TalkRequest + ActiveDialogue)

Tyre re-review (2 items):
- input.rs: same teleport test coverage (overlaps Hoshe #3)
- dialogue.rs: process_confrontation_response now inserts RoutineDeviation
  with DeviationTrigger::Confrontation — symmetric with walk-away path.
  Test updated to verify deviation is recorded.
