Graph: add neutral seeded corpus

[fubhy]

Summary

• add a deterministic primitive-only GraphSpec corpus with fixed PRNG output, named shape and size fixtures, and SHA-256 fingerprints
• add an Effect adapter that preserves insertion order and ordinal-to-public-index mappings, including explicit sparse mutation recipes
• cover deterministic replay, exact grid sizes, fixture validity, fingerprints, rich/simple domains, ordering, and sparse adaptation

Plan

• PR ID: V01
• Depends on: none
• Deferred: benchmark/runtimeperf validation is intentionally out of scope for this cycle

Validation

• pnpm lint-fix
• pnpm test --run packages/effect/test/GraphCorpus.test.ts
• pnpm check
• git diff --check
