- Changed `DEFAULT_RELAY_URL` in `@oh-my-pi/pi-wire` from `wss://relay.omp.sh` to `wss://my.omp.sh` and updated the constants, collab-link, and join-command tests asserting the old origin.
- Added `DEFAULT_SHARE_URL` (`https://my.omp.sh/s`) to pi-wire with its changelog entry; it shares a changed run with the relay constant and is consumed by the upcoming /share work.
- Updated collab-web canonical/OG/twitter URLs in `index.html`, `robots.txt`, `sitemap.xml`, README, and the `local-relay.ts` doc comment to the new domain.
- Refreshed the `/collab` entry in the coding-agent changelog to reference the new relay origin.
- Enabled read-only mode by wiring snapshot.readOnly through AgentDrawer and Composer to block prompts and controls.
- Added read-only indicators in the header and participant titles for view-only sessions.
- Added SEO and app metadata assets by updating index.html head tags, manifest, robots.txt, and sitemap.xml.
- Updated brand presentation by adding new favicon/OG assets and switching theme tokens to new OMP colors.
