docs: add CLAUDE.md project memory

Records the canonical Google Doc for human-only ("only J can do it")
publishing follow-ups so those steps are appended there, not just chat.

+# Project memory — vscode-a2ml
+
+## Human-only ("only J can do it") action items
+
+There is a canonical Google Drive doc for tasks that only Jonathan can do
+(credentials, account-bound steps, anything CI/automation cannot perform):
+
+- **"Things for Jonathan to do — vscode-a2ml publishing"**
+  (Google Doc id `1_M4KmorQDXYgqZkP2S3co1cxdh2VDMGpzeA1uHuPJX8`)
+
+Whenever work concludes with a final step that only Jonathan can perform,
+append it to that doc rather than only mentioning it in chat.
