Stub: Stripe Webhook Integration (Ready for Go-Live)

[jaypatrick]

Stub out Stripe webhook integration for upcoming billing support:

• Add /api/webhook/stripe endpoint using raw body mode (context.req.text())
• Import and wire up basic logic per hono-stripe example (verify signature, parse event)
• Add TODO comments for on-live activation and switching to relevant business logic
• Reference: https://hono.dev/examples/stripe-webhook/

Extendable for planned paid tiers; also serves as pattern for future HMAC-verified webhooks (e.g., GitHub, others).

The GitHub issue outlines the creation of a stub for a Stripe webhook integration to prepare for upcoming billing support. The task involves adding a /api/webhook/stripe endpoint using raw request body mode (context.req.text()), incorporating basic logic for verifying signatures and parsing events as demonstrated in the hono-stripe example, and including TODO comments for enabling live functionality and integrating business logic. The implementation is designed to accommodate planned paid subscription tiers and serve as a reusable pattern for future HMAC-verified webhooks, such as GitHub or other services. For reference, developers can consult the hono-stripe example provided in the linked documentation.
