"""services/notes.py — the inline embedding moved here from the routes (#2056).

Why it moved: embedding was triggered at each REST route and nowhere else, so a
record created through MCP stayed out of semantic search and auto-inject until
the next restart's backfill. Putting it in the service means every caller — REST,
MCP, recurrence, snippets — gets it by construction rather than by remembering.

These test the helper directly. The point of the change is that there is now ONE
place to test.
