chore(cli): bump api-contracts to 0.74.0

[Atchyut Preetham Pulavarthi (theonly1me)]

Overview of Changes

@qawolf/api-contracts 0.74.0 adds finished-attempt artifact lookup, failed-attempt discovery metadata, and superseded run status.

• Pin @qawolf/api-contracts to 0.74.0 and update bun.lock.
• Regenerate the command and run-result documentation and update polling guidance to follow supersededBy.runId.
• Add a minor-release changeset for the new qawolf run getAttemptArtifacts command and run metadata.

Testing

bash scripts/check-naming.sh
bun run typecheck
bun run lint --max-warnings 0
bun run format:check
bun run knip
bun run test
bun run build
bun run build:types-gate

All checks passed with Bun 1.4.2, including 2,673 tests.

• Built in a temporary project copy and verified the Node CLI starts and exposes run getAttemptArtifacts --attempt-id.
• Reran the affected command-generation and documentation tests after updating polling guidance, with 86 passing.
