   Friendly ping: this PR has been rescoped to a **documentation-only** patch 
(+158/-5, two files).
   
   It documents the existing `EXPLAIN` detail variants (`ESTIMATED_COST`, 
`CHANGELOG_MODE`, `JSON_EXECUTION_PLAN`, `PLAN_ADVICE`) — with a dedicated 
section for `CHANGELOG_MODE` covering:
   - the symbols (`I`, `UB`, `UA`, `D`, `PD`) and how to interpret them,
   - how the pattern maps to append-only / upsert / retract stream semantics,
   - a concrete SQL example with sample output,
   - and the relationship to operators (join/agg/dedup) and connector 
capabilities.
   
   No production code or test-plan files are touched, so this shouldn't risk 
the test-plan churn that blocked the earlier revision of this PR. Would any of 
you have a few minutes to take a look?
