docs: add Logto dev environment skill

[wangsijie]

Summary

Add a logto-dev-environment agent skill for bringing up and verifying the local Logto development environment end to end.

The skill documents the reusable workflow for using the machine's default Node.js/pnpm, installing dependencies, starting Postgres, seeding or altering the database, running pnpm start:dev, checking local services, creating the first admin to initialize tenant-level Console configuration, and choosing the right smoke-test path for future feature work.

It also folds the previous sign-in experience demo-app workflow into the new general dev environment skill as an end-user flow testing reference: configure SIE for the path under test, then use /demo-app as a local client entry point to trigger the OIDC sign-in flow. The old overlapping logto-sign-in-exp-demo-app skill is removed.

Adds a new agent skill to standardize bringing up Logto’s local development environment end-to-end, consolidating the prior demo-app / sign-in-experience workflow into a single “dev environment” skill and removing the now-overlapping skill.

Changes:

• Add logto-dev-environment skill with an end-to-end local bootstrap + verification workflow (including /demo-app flow).
• Update skill index and cross-links to point to the new skill.
• Remove the old logto-sign-in-exp-demo-app skill and its reference doc.
