fix: resolve all lint warnings and fix failing playground toolbar test

- Fix playground-toolbar test: URL changed to github.com but test still expected docs.emdashcms.com
- create-emdash: extract selectTemplate() to eliminate unsafe/unnecessary type assertions
- create-emdash: use type-safe Object.keys filter instead of bare cast
- cloudflare/cache: use Reflect.get with typeof guard instead of double type assertion
- x402/enforcer: replace unsafe request cast with Reflect.get type guards for CF bot management
- x402/middleware: suppress unavoidable virtual module any-cast with eslint comment
