Generic case conversion utilities for API and data transformations.

This namespace provides reusable case conversion utilities that handle
transformations between different naming conventions commonly used in APIs:
- camelCase (JavaScript/JSON APIs)
- kebab-case (Clojure idioms)
- snake_case (Database/SQL)

These functions are designed to be nil-safe and handle nested data structures
where appropriate.

Usage:
(:require [wagoe.core.utils.case-conversion :as case-conversion])

(case-conversion/camel-case->kebab-case-map {:userId "123" :tenantId "456"})
;; => {:user-id "123" :tenant-id "456"}

Ids for new app migrations.

Apps and framework libraries share one `schema_migrations` id space, and
framework ids end in an odd second (test/wagoe/migration_ids_test.clj). So
an app id ends in an even one and never collides with a framework id.

Shared PII redaction utilities used by error reporting adapters.

Is a user-supplied redirect target a path on this site? Shared by every
`return-to`, so the rule is written once (BOU-553).

Case conversion that gives the same answer on every JVM.

clojure.string/lower-case and upper-case use the JVM's default locale, so on
tr-TR `I` lowers to a dotless `ı` and `i` uppers to a dotted `İ`. Keys,
headers, emails and SQL names must not change with the server's locale.

Generic type and case conversion utilities.

Value predicates the CLI layer validates arguments with.

It also held a second implementation of validate-with-transform,
validate-cli-args, validate-request and the result accessors — the same
names wagoe.core.validation defined, with a different implementation and no
compiled-schema cache. Nothing outside its own tests called them (BOU-323).

Schema validation goes through wagoe.core.validation, whose validators are
compiled once and cached; result shapes live in
wagoe.core.validation.result.
