-# `pub async fn create_pool(database_url: &str) -> Result<SqlitePool>`
-
-Creates and returns a sqlite connection pool.
-
-Notes:
-
-- Database table names are singular: `activity`, `tenant`, `relay`, `lightning_invoice`
-
-Steps:
-
-- Normalizes `database_url`: a relative `sqlite://` path is resolved under the crate manifest directory (`CARGO_MANIFEST_DIR`); absolute paths and `:memory:` are left as-is
-- Ensures any directory referred to in the (normalized) URL exists
-- Opens the pool with `create_if_missing` enabled
-- Enables WAL journaling (`PRAGMA journal_mode = WAL`)
-- Runs migrations found in the `migrations` directory
