* docs(influxdb3): document how to disable Processing Engine
Add documentation for disabling the Processing Engine in Docker and
systemd deployments. Key points:
- Processing Engine is enabled by default in Docker images and DEB/RPM
- Empty string does not disable — must unset or remove config
- Enterprise: use INFLUXDB3_UNSET_VARS feature
- Core Docker: requires custom entrypoint workaround
- systemd: comment out or remove plugin-dir from TOML config

* docs(influxdb3): add cross-references for Processing Engine defaults
Add notes and cross-references explaining that the Processing Engine
is enabled by default in Docker and DEB/RPM installations:
- plugins/_index.md: Add deployment behavior table and link to disable docs
- get-started/processing-engine.md: Add note with cross-reference
* docs(influxdb3): clarify Processing Engine vs process mode distinction
Add notes explaining that --plugin-dir (Processing Engine activation) and
--mode=process (cluster node specialization) are independent configurations.
* docs(influxdb3): document --plugin-dir auto-enables process mode
- Update clustering, get-started, plugins, and reference pages
- Add example for enabling Processing Engine without --mode=process
- Clarify --mode=process is only needed for dedicated process-only nodes
- Synthesize notes into inline content for better flow in guides
* Update content/shared/influxdb3-reference/influxdb3-processing-engine.md
