Develop against Effect 4.1.2. 15 files changed; local gates and all seven CI jobs pass. Draft awaiting merge approval; no release or merge.

Why

Problem: development still used Effect 4.0, while 4.1 moved the Crypto API.

• Keep development dependencies aligned at 4.1.2.
• Make the database package's new minimum explicit.
• Preserve the query builder's older minimum with executable proof.

Key Changes

Dependency upgrade:

• Pin workspace Effect and Platform/SQL packages to 4.1.2.
• Require Effect >=4.1.2 <4.2.0 for effect-db.
• Allow Effect >=4.0.0 <4.2.0 for effect-qb.

Native crypto migration:

• Use the Effect digest service for migration checksums.
• Provide the native Node digest implementation for CLI and Promise APIs.
• Remove unused crypto requirements from source discovery.
• Keep checksum format and line-ending normalization unchanged.

Compatibility proof:

• Test packed packages against the exact development version.
• Independently install effect-qb with Effect 4.0.0, compile public type fixtures, and execute the Node SQLite smoke.
• Document the different development and consumer requirements.

Risks & Testing Needed

Breaking change: effect-db drops Effect 4.0 support.
→ Effect-based migration readers now need Digest.Digest from effect/crypto; provide NodeCrypto.layerDigest alongside platform services.

Unchanged: CLI and Promise APIs provide the services automatically. effect-qb keeps its 4.0 minimum.

Not tested locally: Node 22 and 26.
→ All Node 22/24/26 verification and integration CI jobs passed on 5186197.

Verification note: an overlapping local package rebuild invalidated the first integration run. A serialized rerun passed all 197 tests without a product workaround.

Build status: all seven CI jobs passed; local build, 741 tests, types, packed consumers, layout checks, and 197 integration tests passed on Node 24.22.1.
