chore(release): v0.24.3

[mylukin]

Summary

• bump root package version from 0.24.2 to 0.24.3
• release Route cheap low-risk turns to economy #451 cheap-model low-risk classifier routing changes

Version choice

• patch bump: classifier/config routing optimization, no breaking API or feature-surface expansion requiring a minor bump
• v0.24.2 already exists for the previous settings-width release, so this uses the next patch version

Verification

• node -p "require('./package.json').version" -> 0.24.3
• corepack pnpm exec vitest run packages/shared/src/smoke.test.ts packages/shared/src/ci-workflow.test.ts packages/shared/src/dockerfile.test.ts packages/shared/src/compose.test.ts
