v1.0.0

Initial release.

Adds Langfuse's full self-hosted stack (web, worker, Postgres, ClickHouse,
Redis, MinIO) as a DDEV add-on, on your project's own Docker network.

• Generates all required secrets on first install (openssl rand) into
  .ddev/.env.langfuse -- no hand-edited CHANGEME placeholders.
• Headlessly bootstraps an org, project, admin user, and API keypair via
  Langfuse's LANGFUSE_INIT_* env vars.
• Prints admin login + API keys after install, and again via
  ddev langfuse-credentials.
• Verified end-to-end with bats ./tests/test.bats against a real
  DDEV/Docker install.

See the README
for installation and usage.
