Implement event normalisation and semantic action inference for the Phase 1 step set

[kalen-releasedgroup]

Summary

Transform raw recording events into a cleaned sequence of meaningful actions suitable for author review.

Scope

• Remove technical noise, merge related input bursts, and associate actions with observed outcomes.
• Infer semantic actions for the MVP scope such as navigation, save, submit, open modal, and basic selection flows.
• Persist normalized step data for draft scenario creation.

Requirement Links

• FR-INF-001, FR-INF-002
• Sections 5.3.2, 7.3

Dependencies

• Sprint 2 recording persistence

Exit Criteria

• Raw recordings can be transformed into meaningful ordered steps.
• The normalized step set is persisted and available to the UI.
• Noise is reduced without losing business-critical actions.
