fix(scaffold): emit .gitattributes and default npm scope to @TMHS

Two defects hit and worked around during the godot-correctness-mcp birth, now
fixed at the source so no future born repo repeats them:

- Add templates/gitattributes.j2 and emit it for every born repo (both types,
  alongside .gitignore): normalizes LF for ts/js/json/md/yml/yaml and marks
  .gz/.wasm artifacts binary. Prevents CRLF phantom diffs on .json and mangled
  committed binary artifacts.
- Default npm scope corrected from @{{ repo_owner | lower }} (-> @TMHSDigital)
  to @TMHS in package.json.j2 and site.json.j2. The GitHub org references
  (TMHSDigital in URLs) are unchanged and correct.

License already emits CC-BY-NC-ND-4.0 (package.json + LICENSE); verified, no
change. STANDARDS_VERSION unchanged (not a standards change); VERSION bumped
1.17.1 -> 1.17.2 per the meta-repo contract for a scaffold fix.
