docs: include img2threejs in stocktake table and sync readme diagram (#22)

## Summary
Closes the leftover stocktake audit gap in `docs/stocktake-1.8.3.md` without changing existing verdicts or bumping versions.

- **`docs/stocktake-1.8.3.md`**:
  - Update intro: measured tree is now 47 model + 16 manual = 63. Cites `66eebe9` / PR #21; earlier rows were taken against `4b1fd7f2` / #18 protocol.
  - Insert row for `img2threejs` (`KEEP`, model-invoked) in alphabetical order after `hyperframes`.
  - Update tallies: 57 KEEP, 2 COMPRESS, 4 UPDATE, 0 MERGE, 0 RETIRE, Total 63.
  - Note in follow-ups: `img2threejs` added post-#21; not part of the original 1.8.3 execution pass.
  - Recounted and verified by parsing table rows via script.
- **`CHANGELOG.md`**:
  - Add bullet under `## Unreleased` documenting `img2threejs` inclusion in the stocktake doc (63 rows, KEEP).
- **`README.md`**:
  - Sync architecture diagram from `46 automatic` to `47 automatic`.

 - `docs/warehouse-inventory.md`: `DEFER` no longer promotes to `NEW` without an existence pass and a no-skill baseline. Capability drift is grounds for `COMPRESS`/`RETIRE`, never a twin skill. Wave 1–3 counts are unchanged.
 - Document NVIDIA SkillEvaluator as `FOREIGN_ON_DEMAND`: never installed, absent is not a doctor failure, and a malformed MCP entry still fails closed.
 - Execute the stocktake protocol across all 62 catalog items and record it in `docs/stocktake-1.8.3.md`: one verdict per item, 56 `KEEP`, 2 `COMPRESS`, 4 `UPDATE`, 0 `MERGE`, 0 `RETIRE`. `MERGE` is zero on measured evidence, the highest description overlap being 0.359 Jaccard, below the 50% warn line. No item is retired without a no-skill baseline; five candidates are recorded as blocked on the A/B gate.
+- Stocktake documentation (`docs/stocktake-1.8.3.md`) now includes `img2threejs` (63 rows, KEEP).
 - `README.md`: document optional `stitch` MCP alongside `serena` and `exa`. Enabled only by `opencode-bf stitch enable`, keys referenced as `{env:STITCH_API_KEY}` or omitted with `--oauth`, not an owned core server and not a production UI implementer, absent is not a doctor failure.
 - Retire the predecessor `GrokBuild` host-product name from four skill bodies (`ask-matt` description, `chrome-devtools-axi` heading, `adhd`, `visual-studio`). `ask-matt` matters most: its description loads on every session. Tool-family references that name an image/video contract rather than the host are left intact.
 - `chrome-devtools-axi`: drop a `$HOME/.grok/bin` fallback that contradicted `rules/00-routing.md` ("Do not depend on `~/.grok` at runtime") and reconcile two duplicated invocation blocks. Port `9223`, the `HEADED`/`AUTO_CONNECT` prohibition, and the never-fall-back-to-Google-Chrome fence are unchanged.
