- New docs/OBSERVABILITY.md: developer-facing guide with a "where to look
for what" table, common LogQL queries, trace exploration workflow,
log→trace correlation via traceId links, and a signal summary table
- Link from DEPLOYMENT.md §4 (ops section now points to dev guide) and
from CLAUDE.md Infrastructure section
- Fix stale DEPLOYMENT.md env var table: OTEL_EXPORTER_OTLP_ENDPOINT
now documents port 4318 (HTTP) not 4317 (gRPC); add the three new
env vars wired in this PR (OTEL_LOGS_EXPORTER, OTEL_METRICS_EXPORTER,
MANAGEMENT_METRICS_TAGS_APPLICATION) with their rationale
- Fix stale obs-tempo service description (port 4318, not 4317)
