Add v3 as a valid group autorouterVersion

[seveibar]

Motivation

• Support the new autorouter v3 option so group props accept and validate the newer autorouter version at both type and runtime.

Description

• Added "v3" to the autorouterVersion TypeScript union on SubcircuitGroupProps in lib/components/group.ts.
• Added "v3" to the corresponding Zod enum validation for autorouterVersion in lib/components/group.ts.
• Regenerated generated/COMPONENT_TYPES.md and generated/PROPS_OVERVIEW.md so the docs reflect the new "v3" value and ran project formatting.

Testing

• Ran the generation scripts bun scripts/generate-component-types.ts, bun scripts/generate-manual-edits-docs.ts, bun scripts/generate-readme-docs.ts, and bun scripts/generate-props-overview.ts which completed successfully.
• Typechecked with bunx tsc --noEmit which passed.
• Ran unit tests bun test tests/group.test.ts and bun test tests/autorouter.test.ts and both suites passed.
• Ran bun run format to apply formatting.
