- 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.
