Add INFLUXDB3_ prefixes to CLI environment variables with deprecation notes

[Copilot]

Adds INFLUXDB3_ prefixes to 17 environment variables in the CLI configuration documentation, marking unprefixed names as deprecated while maintaining backward compatibility.

Changes

Updated content/shared/influxdb3-cli/config-options.md:

• Logging variables (3): LOG_FILTER, LOG_DESTINATION, LOG_FORMAT
• Object storage variables (6): OBJECT_STORE_CONNECTION_LIMIT, OBJECT_STORE_HTTP2_ONLY, OBJECT_STORE_HTTP2_MAX_FRAME_SIZE, OBJECT_STORE_MAX_RETRIES, OBJECT_STORE_RETRY_TIMEOUT, OBJECT_STORE_CACHE_ENDPOINT
• Tracing variables (8): TRACES_EXPORTER, TRACES_EXPORTER_JAEGER_AGENT_HOST, TRACES_EXPORTER_JAEGER_AGENT_PORT, TRACES_EXPORTER_JAEGER_SERVICE_NAME, TRACES_EXPORTER_JAEGER_TRACE_CONTEXT_HEADER_NAME, TRACES_JAEGER_DEBUG_NAME, TRACES_JAEGER_TAGS, TRACES_JAEGER_MAX_MSGS_PER_SECOND

Pattern

All environment variable tables now follow this format:

influxdb3 serve option	Environment variables
--log-filter	INFLUXDB3_LOG_FILTER (preferred) LOG_FILTER (deprecated; supported for backward compatibility)

Example code updated from:

export LOG_FILTER=info

to:

export INFLUXDB3_LOG_FILTER=info
