## Which issue does this PR close? - Closes N/A ## Rationale for this change `EXPLAIN ANALYZE` on a `PiecewiseMergeJoin` always reports `join_time=0` and, for classic joins, `output_rows=0` / `output_bytes=0.0 B`, so PWMJ plans can't be profiled like other joins. ## What changes are included in this PR? - Classic stream: time probe-phase work under `join_time` (started only after the streamed input's poll returns `Ready`) and record output metrics via `record_poll` - Existence stream: same `join_time` coverage for the scan and final pass - `elapsed_compute` picks both up via the existing `BuildProbeJoinMetrics` drop ## Are these changes tested? Yes. Classic tests now assert `assert_join_metrics!`, the existence final-pass test pins `join_time > 0`, and a new test verifies `join_time` excludes streamed-input wait. `explain_analyze.slt` shows the real `output_bytes`. ## Are there any user-facing changes? No (PWMJ is experimental and off by default). 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
