docs(adr): add Implementation Status & Integration to ADR-136..146

Weaves the three framing points into every ADR in the series:
- skeleton/scaffolding (data contracts + trust/privacy/audit machinery +
  algorithms; real, tested, compiling) that existing sensing code plugs into
- Built (tested building block) vs Integration glue (not yet on the live 20 Hz
  path) — per-ADR, with commit + issue references
- trust throughline (traceable evidence, sensor agreement, calibration
  provenance, auditable privacy)
ADR-136 §8 carries the full series framing; 137-146 carry per-ADR status.
