fix: republish bias-testing API on @euconform/core as 1.4.0

[Hiepler]

Problem

The Apr 15 release (760d327 chore: release) bumped @euconform/core from 1.2.0 to 1.3.0 — but @euconform/core@1.3.0 had already been published on Apr 10 from the ECEF release. As a result:

• The bias-testing additions (./datasets export, CapabilityCache, loadCrowsPairsDataset, sideEffects: false) never made it to npm.
• npm view @euconform/core@1.3.0 exports does not list ./datasets.
• packages/core/CHANGELOG.md ended up with a duplicate ## 1.3.0 header where the bias-testing entry was prepended above the existing ECEF section.

Root cause: a manual rollback of core/package.json from 1.3.0 → 1.2.0 caused Changesets to recompute 1.2.0 + minor = 1.3.0, colliding with the existing tag.

Fix

• New changeset bumping @euconform/core as minor → 1.4.0 with the bias-testing API.
• Internal-dependency patches: @euconform/cli → 1.1.1, @euconform/web → 1.2.3 (via updateInternalDependencies: "patch").
• Removed the duplicate ## 1.3.0 block from packages/core/CHANGELOG.md. The bias-testing description is regenerated under the new ## 1.4.0 section when the changeset bot runs.

pnpm exec changeset status --verbose confirms:

patch: @euconform/web 1.2.3, @euconform/cli 1.1.1
minor: @euconform/core 1.4.0

Test plan

• pnpm lint — clean (277 files)
• pnpm check-types — 9/9 tasks pass
• pnpm test — 262 tests pass (70 web + 164 core + 28 cli)
• pnpm build — 7/7 packages succeed
• After merge: Changesets bot opens release PR; merging it publishes @euconform/core@1.4.0 and @euconform/cli@1.1.1 to npm.
