Mighty Mouse v0.2.6

Mighty Mouse v0.2.6

Mighty Mouse v0.2.6 completes architecture seam deepening across Agent
Execution, response application, and Signal telemetry while preserving public
compatibility paths.

Release changes

• Established response application as authoritative for supported Agent and
  non-Agent callers.
• Routed supported loop callers through canonical SignalTelemetry while
  retaining compatibility facades.
• Contracted legacy parser ownership at response application boundary.
• Added characterization, inventory, and compatibility coverage for migrated
  seams.

Limits

Compatibility facades remain intentionally in place until retirement evidence
proves removal safe. Original local-model orchestration and evaluation-only
boundaries remain separately classified.
