Mighty Mouse v0.2.4

Mighty Mouse v0.2.4

Mighty Mouse v0.2.4 establishes canonical architecture seams behind existing
public and runtime contracts.

Release changes

• Established PolicyEngine as the canonical policy-selection seam and added
  canonical status projection.
• Added PolicyMutationEngine as the typed mutation-generation seam.
• Added SignalTelemetry as the canonical v2 Signal construction and emission
  seam.
• Added an explicit AutoresearchCycle boundary for bounded cycle execution.
• Completed the expand-contract compatibility migration while preserving public
  APIs, persistence behavior, evaluator boundaries, and runner-lock semantics.
• Restored the missing Scope import so CI collection succeeds across Python
  3.10–3.13.

Limits

Legacy mutation orchestration still couples filesystem, replay, and log
behavior. The evaluator metric_telemetry.json remains separate from v2
Signal telemetry. Runner-lock scope remains outside the individual cycle.
Compatibility adapters remain intentionally in place where contraction would
change behavior.
