Shay 568face63e feat(reasoning): field-wedge foundation — f64 embedding, lineage firewall, INV-27
Phase 0 of the field-reasoner wedge — net hardening regardless of the
experiment's outcome.

- algebra/cga.py: embed_point gains a dtype kwarg (f32 default byte-unchanged;
  cl41.geometric_product already preserves f64) + read_scalar_e1 projective
  dehomogenization read-back (weight-invariant; correct for dilations, where a
  raw distance-from-origin is wrong) + EMBED_EXACT_MAX pinned magnitude ceiling.
  f32 silently collapsed integer coordinates past ~1e4.
- core/reasoning/evidence.py: verify_tier2_agreement now keys independence on a
  reader_lineage pathway token (refuses SAME_READER_LINEAGE), replacing the
  label-only len(set(signatures))<2 check a single reader could satisfy by
  relabeling. reader_lineage is excluded from canonical serialization, so the
  entailment trace_hash is unchanged.
- tests INV-27: transitive reader-disjointness over TIER2_READER_PATHWAYS makes
  the lineage check load-bearing (distinct lineage => proven import-disjoint
  pathway). The two seeded readers share zero transitive first-party modules.

Green: smoke 87, algebra 82, cognition 121, 53 architectural invariants,
reasoning/deductive/r1 50; 16 new f64-exactness tests; zero regressions.
