Squash merge of 76 commits from loops/minikanren. Adds lib/minikanren/ — a complete miniKanren-on-SX implementation built on top of lib/guest/match.sx, validating the lib-guest unify-and-match kit as intended. Modules (20 .sx files, ~1700 LOC): unify, stream, goals, fresh, conde, condu, conda, run, relations, peano, intarith, project, nafc, matche, fd, queens, defrel, clpfd, tabling Phases 1–5 fully done (core miniKanren API, all classic relations, matche, conda, project, nafc). Phase 6 — native CLP(FD): domain primitives, fd-in / fd-eq / fd-neq / fd-lt / fd-lte / fd-plus / fd-times / fd-distinct / fd-label, with constraint reactivation iterating to fixed point. N-queens via FD: 4-queens 2 solutions, 5-queens 10 solutions (vs naive timeout past N=4). Phase 7 — naive ground-arg tabling: table-1 / table-2 / table-3. Fibonacci canary: tab-fib(25) = 75025 in seconds, naive fib(25) times out at 60s. Ackermann via table-3: A(3,3) = 61. 71 test files, 644+ tests passing across the suite. Producer/consumer SLG (cyclic patho, mutual recursion) deferred — research-grade work. The lib-guest validation experiment is conclusive: lib/minikanren/ unify.sx adds ~50 lines of local logic (custom cfg, deep walk*, fresh counter) over lib/guest/match.sx's ~100-line kit. The kit earns its keep ~3× by line count.
