docs(#171): close the issue — user visual gate PASSED ("Looks good, ship it")

Three slices: 5bd2b8bc (R5-V3 sticky binding + real radii) + 7a823176
(NPC UP-snap suppression while stuck, TS-44) + 69966950 (deep-overlap
back-off sign pin, AP-82). ISSUES entry marked DONE; r5-wiring-handoff
V3 status = gate passed; ACDREAM_PROBE_STICKY documented in CLAUDE.md's
diagnostic env-var list (kept as permanent gated diagnostics — the
PhysicsDiagnostics probe-family pattern, off by default).
