docs(agents): fix 5 review issues in testorg_plan.md

H-1: Change D-1 status-table dependency from Phase B to Phase C;
     the CMakeLists.txt example uses post-C-1 filenames, so D-1 must
     run after C-1, not immediately after Phase B.  Also update the
     Phase D header to state this dependency explicitly.

H-2: Move undirected_dfs.cpp row to its correct alphabetical position
     in the Step C-1 rename table (after tiernan_all_cycles, not
     between finish_edge_bug and graph).

M-1: Rename A-3 section heading from 'SGB/LEDA' to 'SDB/LEDA' to
     match the actual Jamfile flag name (-sSDB=).

M-2: Remove unused 'import path ;' from the B-1 concepts Jamfile
     example — no path.* rules are called in that sub-Jamfile.

M-3: Add a Multi-variant tests block to the D-1 CMakeLists.txt snippet
     explaining that bgl_test() cannot handle graph_1..9 /
     property_iter_1..9, with an explicit add_executable / add_test
     pattern for those cases.

 ### Step C-1 — Rename test files to `*_test.cpp`
 
-Rename every runtime test file that does not already end in `_test.cpp` or
-`_cc.cpp`. Use the table below as a starting point, then run a final search for
-any remaining top-level `test/*.cpp` runtime tests that still use bare or
-hyphenated names before closing the step.
+Rename every current `[ run ... ]` target in `test/Jamfile.v2` that does not
+already end in `_test.cpp` or `_cc.cpp`, except for the `*2` variants deferred
+to Step C-3 and the explicit framework-file exception noted below. The table
+below was verified programmatically against the current Jamfile runtime
+inventory, normalized through the Phase A-3, A-4, and B-4 path moves that must
+already be in place before Phase C starts. If the Jamfile changes before this
+step lands, regenerate the inventory and refresh the table in the same commit.

+Explicit exceptions and deferrals:

+- `test/test_graphs.cpp` is a framework-driver exception for now. Keep it as-is
+  unless the suite is reworked enough to justify a clearer driver name.
+- Defer `test/transitive_closure_test2.cpp`,
+  `test/vf2_sub_graph_iso_test_2.cpp`, and
+  `test/weighted_matching_test2.cpp` to Step C-3, which decides whether each
+  file is merged away or renamed to a descriptive `_test.cpp` name.
+- Do not count compile-only or currently unlisted files toward this runtime
+  inventory. In the current tree that includes `copy.cpp`, `swap.cpp`,
+  `property_iter.cpp`, `dimacs.cpp`, `filtered_graph_properties_dijkstra.cpp`,
+  `undirected_dfs_visitor.cpp`, and `bidir_vec_remove_edge.cpp`.
