chore(release): 0.4.0

[rodrigobnogueira]

Version bump for the 0.4.0 release: OutboxWaker (in-process wake, #20) + WakeSocketServer/WakeSocketClient (cross-process same-machine wake, #21). Package 0.3.1 → 0.4.0, sample pins synced, CHANGELOG stamped. release:check green locally (pack validation + packed-consumer smoke). After merge: tag v0.4.0 → release workflow publishes with provenance.

Note: Release and security checks is expected red on the pre-existing website (docusaurus) advisories — unrelated to the package; the published-tarball audit is green.

🧭 Cognitive complexity is reported as a review signal, not a merge gate. Prefer small, intention-revealing refactors when complexity rises.
