Remove obsolete N-way collision tests, add focused hash ID tests

- Remove beads_nway_test.go (92s of obsolete sequential ID collision tests)
- Remove beads_twoclone_test.go (already skipped tests)
- Add beads_hash_multiclone_test.go (6s, tests hash ID multi-clone sync)
- Fix init.go git hook to remove --resolve-collisions flag

Result: 87% faster test suite (96s → 12s for full suite)

Hash-based IDs prevent collisions by design, making extensive N-way
collision resolution tests unnecessary. New tests verify that:
- Multiple clones can sync without ID collisions
- Identical content deduplicates correctly
