Subject: [PATCH 1/2] feat(graph): add SPO triple store with bitmap ANN,
 TruthGate, semiring traversal + 7 ground truth tests

Implements the full SPO (Subject-Predicate-Object) graph primitives stack:

- graph/fingerprint.rs: label_fp() with 11% density guard, dn_hash(), hamming_distance()
- graph/sparse.rs: Bitmap [u64;BITMAP_WORDS] (fixes old [u64;2] truncation), pack_axes()
- graph/spo/truth.rs: TruthValue (NARS frequency/confidence), TruthGate (OPEN/WEAK/NORMAL/STRONG/CERTAIN)
- graph/spo/builder.rs: SpoBuilder with forward/reverse/relation query vector construction
- graph/spo/store.rs: SpoStore with 2^3 projection verbs (SxP2O, PxO2S, SxO2P), gated queries, semiring chain walk
- graph/spo/semiring.rs: HammingMin semiring (min-plus over Hamming distance)
- graph/spo/merkle.rs: MerkleRoot, ClamPath, BindSpace with verify_lineage (known gap documented) and verify_integrity
- graph/mod.rs: ContainerGeometry enum with Spo=6

Ground truth integration tests (7/7 pass):
1. SPO hydration round-trip (insert + forward/reverse query)
2. 2^3 projection verbs consistency (all three agree on same triple)
3. TruthGate filtering (OPEN=2, STRONG=1, CERTAIN=0 for test data)
4. Belichtung prefilter rejection rate (<10 hits from 100 edges)
5. Semiring chain traversal (3 hops with increasing cumulative distance)
6. ClamPath+MerkleRoot integrity (documents verify_lineage no-op gap)
7. Cypher vs projection verb convergence (SPO side validated)

31 unit tests + 7 integration tests, all passing. Clippy clean.
