docs(kiro): status notes -- ai-service-plane complete, contributor-scan paused, finding-feedback-loop design unapproved; stale lines

Legacy inventory 2, the six STATUS NOTE items (the archive README row landed with the R2 commit).
ai-service-plane: 11 of 11 tasks checked, spec.json phase set to implementation-complete as 5b96199
did for four other specs. contributor-scan: dated note in requirements.md -- paused since 2026-09-23,
27 of 51 tasks, v1.2.0-alpha.1 NO-GO, remaining tasks wait on pre-push M2/M3. finding-feedback-loop:
dated note -- dormant, design unapproved since 2026-09-09, depends on the paused spec. The steering
overview's spec table carries the same three states, its leftover 2026-09-09 module-count line is
removed and the collected-test count is the measured 2,023. docs/memory-and-detection.md names the
archive path of model_sinks, the one stale script name left in docs after 067adb9.
