skills: add obsidian-sorter; point project-docs at the inbox workflow

- new obsidian-sorter skill: file notes via the 010 inbox on .27
- project-docs now writes to the inbox and lets the sorter choose the
  folder + type, instead of the retired <vault>/Projects/ path
- obsidian-note template gains title/type/created and keeps skills:/tools:

skills/project-docs/templates/obsidian-note.md.tpl

+NOTES FOR THE AGENT WRITING THIS NOTE
+  * `type: note` is intentional — this note is written into the INBOX and the
+    obsidian-sorter assigns the real type from its final folder.
+  * Keep `skills:` and `tools:` — they are custom fields the sorter preserves.
+  * Do NOT add a `type` other than `note`, and do NOT choose a folder.
+  * Add the `project` tag so the sorter constrains it to the projects bucket.
