v1.5.3

Features

• Discovery request/response parsing — Beacon now parses DISCOVER_REQ/DISCOVER_RESP control payloads from the mesh, feeding directly into neighbor data.
• Neighbor SNR tracking — a new optional snr column on node_neighbors, now populated from three independent sources:
  • discovery responses observed by Beacon
  • zero-hop adverts seen directly by observers
  • hop pairs derived from TRACE packets
• Observer online check uses last seen — ingest now factors in an observer's last-seen timestamp when determining online status, rather than relying solely on connection state.

Fixes

• Node summary neighbor counts — deduplicated neighbor counts in node summaries that were previously inflated by duplicate rows.
• Release image publishing — fixed the GitHub Actions release workflow so built images are pushed to the public registry correctly. (Thanks, @MrAlders0n!)

Maintenance

• Bumped meshcore-go to v1.0.8.
• SECURITY: Bumped github.com/go-chi/chi/v5 from v5.2.2 to v5.2.4 (dependabot).
• Documented the remaining parsed ingest payload structs.
• Added the new neighbor snr field to the swagger docs.
