Can I vibecode Mem?

Add an importer for a Mem export to the notes app in this folder. Requirements:

- A command `notes import-mem <path>` that accepts a folder of Markdown files or one large
  Markdown file; for a single file, split it on top-level headings into separate notes.
- Take the title from the first heading or the file name, keep created dates from front matter
  when present, and keep any collection names found in the file path or front matter as collections.
- Embed every imported note after saving, in batches, with a progress line per batch.
- `--dry-run` is the default and prints how many notes it would create; `--apply` writes.
  Running it twice must not duplicate notes.
- Update the README with the Mem export steps.

Add voice capture to the notes app in this folder. Requirements:

- A record button in the browser (`MediaRecorder`) that uploads the audio to a local endpoint
  and transcribes it with a whisper.cpp server listening on WHISPER_URL in .env.
- Save the transcript as a note with the audio file kept in ./data/audio/ and linked from the note;
  a model call tidies the text into paragraphs but the raw transcript stays in a collapsed block.
- A size limit per recording and a clear error when the whisper server is not running.
- Update the README with how to start whisper.cpp and which model size to try first.

Add a weekly review to the notes app in this folder. Requirements:

- A job (`node-cron`) at REVIEW_DAY and REVIEW_TIME in .env that collects notes created or edited
  in the last 7 days and asks the model for a summary: themes, open tasks, notes worth linking.
- Save the result as a new note titled with the week, tagged review, with links to every note it
  mentions.
- A "run review now" button, and a log of each run with the notes included and the model used.
- Update the README.

Add email capture to the notes app in this folder. Requirements:

- Poll one IMAP folder named in .env (`imapflow`); each new message becomes a note with the
  subject as the title and the plain-text body, with attachments listed but not stored.
- Skip messages already imported (by Message-ID) and cap the body at 20,000 characters.
- Mark processed messages as read; never delete or move anything in the mailbox.
- Update the README with the app-password steps for Gmail and a note that the mailbox
  credentials stay in .env.
