User story

As a practitioner, I want an integrated chat inside a case, so that all conversation stays E2EE-encrypted within Matrix and linked to the case.

Acceptance criteria

Integration

matrix-js-sdk integrated into the SvelteKit app as a client-side module.
On case detail page load, the Matrix client joins the room associated with the case.
E2EE keys bootstrapped per device (SSSS recovery phrase prompt on first login).

Chat features

Send and receive text messages in real time.
Markdown rendering (safe subset), link preview off by default.
Typing indicators and read receipts.
Scrollback loading with infinite scroll.
Mentions (@display-name).

UX

Unread count shown on the case list row.
Notification sound and browser notification (opt-in).

Tests

Playwright: two browser sessions chat in the same case room with messages appearing within 2 s.
Unit test for message rendering sanitization.

Out of scope

Attachments (issue #17).
Video (issue #16).
Bridge to MSSanté (v0.3).
