docs: record the fourth pass in the review ledger

Batch H, six new CC0 2D sources against the top-down gap. Records that
perspective was decided by opening each pack's sample image rather than its
description, since no Kenney page states a projection in text, and that the
4-directional character half of the gap is still open because nothing added
claims four-direction walk cycles.

+- Executed: **6 new 2D entries**, all CC0 and all `active`. Entry count 294 -> 300.
+  `kenney-micro-roguelike` (8x8, `top_down`), `kenney-tiny-battle` (16x16, `top_down`),
+  `kenney-tiny-town`, `kenney-roguelike-rpg-pack`, `kenney-roguelike-characters` and
+  `armm1998-zelda-like` (all `isometric_3_4`). `top_down` 1 -> 3, and two of the three
+  are now `active` CC0 rather than a lone `needs-review` aggregator.
+- Method worth repeating: **perspective was decided by opening each pack's sample
+  image**, because no Kenney asset page states a projection in text. That is how the
+  split was found. Micro Roguelike and Tiny Battle are genuinely orthographic; Tiny
+  Town and the Roguelike/RPG pack draw facades above an overhead ground plane and are
+  3/4. Filing all of them as top-down because they are overhead RPG tiles would have
+  been wrong, and reading only the descriptions would have produced exactly that error.
+- **The character half of the gap is still open.** It was stated as "CC0 4-directional
+  top-down character sprites" and nothing added here claims four-direction walk cycles.
+  Kenney Roguelike Characters is front-facing 3/4 sprites with variants; the ArMM1998
+  submission says "Character with sword animation and character tamplet" without
+  enumerating directions. Both entries say so in their notes. Confirming directional
+  coverage means downloading and opening the sheets, which no pass has done.
+- Deferred, unchanged: `tenacity`'s licence (Codeberg 403s automated requests), the
+  eight decision-support clusters without comparison lines, the three deliberately
+  untagged tile packs, and the scope question about `camera_perspective` on
+  `characters` and `3d`.
+- Next highest-value action: **open the character sheets** for
+  `kenney-roguelike-characters`, `armm1998-zelda-like` and `ninja-adventure` and record
+  what directional coverage each actually ships. That is the one remaining question
+  behind the original task-test gap, and it is now the only thing standing between the
+  catalog and a confident answer to "where do my top-down characters come from".
