feat: include memory ID in store/update response text

Include the full memory ID in the response text of `memory_store` and
`memory_update` tools so the AI model can verify successful persistence
and reference specific entries.

- `memory_store`: add `(ID: <uuid>)` to response text
- `memory_update`: show full ID instead of truncated 8-char prefix

Closes #139
