* feat(website): rework sponsorship with homepage sponsor spots
The founder note now states how the project is funded (sponsorship and
Paseo Hub) instead of describing the product, and the same note and
backing links render on the homepage and /sponsor from one module so the
two cannot drift.
Companies can sponsor one of four homepage logo spots at $500 a month
through Stripe rather than GitHub Sponsors, because they need invoices
and a vendor relationship. The spots render as placeholders until sold;
approving a sponsor is an entry in src/data/sponsors.ts. The checkout
URL is a placeholder until the Stripe Payment Link exists.
* feat(website): point sponsor spot checkout at the Stripe payment link
* docs(readme): add a sponsors section
* docs(readme): add the sponsors section to the translated READMEs
* docs(website): document the sponsor approval and Stripe cap workflow
* refactor(storage): remove chat rooms and agent loops
This is the prerequisite cleanup for the storage backend migration. Legacy wire schemas remain temporarily so mixed-version peers can still parse old messages, while daemon callers now use query-shaped AgentStorage methods that can map directly to SQL later.
* test(cli): remove retired chat and loop coverage
