chore: release v0.2.0

Production-readiness pass: security hardening, performance improvements,
new services (send_message, set_repeat, refresh_library), diagnostics,
reauth flow, image proxy, per-instance device IDs, exponential WS
reconnect backoff, ID validation, stale device cleanup, and supporting
integration plumbing. Three rounds of independent code review applied.

See RELEASE_NOTES.md for the full changelog.
